Your competitor drops their price by $5. Your repricing tool matches it. Their tool sees your new price and drops again. You drop again. Three hours later, a product you were selling for $149 is listed at $89 and you are wondering how to explain the margin collapse to your accountant.
This is not a hypothetical. It happens on Amazon regularly. It happens on Google Shopping. And the fear that it could happen to you is one of the most common reasons Australian store owners hold back from automating their pricing at all.
That fear is based on real risk. But it is also based on a misunderstanding of how good dynamic pricing actually works. Here is the full picture — including the part nobody talks about: that a well-configured system raises your prices just as often as it lowers them.
How the Race to the Bottom Actually Starts
Unconstrained repricing — matching the cheapest price available with no lower limit — is genuinely dangerous. When two or more sellers in the same market run automated repricers set to "always beat the lowest price," the result is a downward spiral that can hit rock bottom within hours.
The mechanism is straightforward. Seller A drops to $99. Your tool sees $99 and drops to $98.50. Seller A's tool sees $98.50 and drops to $98. This continues until one of you runs out of stock, goes out of business, or — in the best case — hits a floor they had the foresight to configure before they started.
The problem is not dynamic pricing. Dynamic pricing is just a tool that responds to market signals. The problem is dynamic pricing without constraints. A car without brakes is not a car you should be driving — but the solution is adding brakes, not avoiding cars.
Race-to-the-bottom spirals are most common when a new, aggressive competitor enters your market and uses repricing without any floor configuration. One unconstrained competitor can pull your prices down even if your own rules are well-designed. This is why floors are non-negotiable, not optional.
The Real Cost Beyond Discounting
The immediate margin hit is obvious. Two less-discussed costs compound the damage over time.
Customer conditioning
When your store consistently holds the lowest price in a category, customers begin to expect it. You have trained them that your price floor is somewhere near cost. Walking prices back up after a race-to-the-bottom period is harder than it sounds — customers who bought at $89 feel aggrieved when they see $119 six months later. Recovering price positioning requires more than just raising the number.
Supplier and brand relationships
For stores selling branded products, being the perpetually cheapest option creates problems upstream. Many manufacturers and distributors have Minimum Advertised Price (MAP) policies specifically designed to prevent this. Consistently pricing below MAP — even accidentally through automated repricing without proper floors — can cost you wholesale access. Some brands will pull distribution from stores that persistently damage their price positioning in the market. Losing a major supplier relationship is a significantly worse outcome than a few weeks of compressed margin.
What a Race to the Bottom Actually Costs
Here is a real scenario illustrating the damage.
A store selling outdoor furniture had no price floor configured on their best-selling lounge set. A new competitor entered the market running aggressive automated repricing — no floor, pure "beat by $1" logic on every match. Over three weeks, the market price for that lounge set spiralled from $849 to $699. Neither store sold meaningfully more volume. They split essentially the same weekly demand at a $150 lower price point.
| Week | Your Price | Competitor Price | Weekly Units Sold | Weekly Margin Lost |
|---|---|---|---|---|
| Before competitor | $849 | — | 8 | — |
| Week 1 | $799 | $798 | 7 | $350 |
| Week 2 | $749 | $748 | 8 | $800 |
| Week 3 | $699 | $698 | 8 | $1,200 |
At 8 units per month at the floor price of $699, that was $1,200 in monthly margin lost permanently, with no corresponding increase in sales volume. The competitor eventually ran out of stock and paused their listing. The store raised their price back to $799 — but the three weeks of unnecessary discounting represented real, unrecoverable revenue.
A floor set at $799 would have held the price there throughout. The competitor's unconstrained repricing would not have dragged the store down. And when the competitor went out of stock, PriceSpy would have lifted the price back to $849 automatically.
A race to the bottom does not increase your sales volume. It splits the same weekly demand at a lower price point, with both parties losing margin they did not need to give away. Sales volume is driven by product availability, trust, and fulfilment — not by being $1 cheaper than your nearest competitor.

Price Floors: Your Pricing Safety Net
A price floor is the minimum price PriceSpy will ever set for a product. No market signal, no competitor action, no automated rule will push a product below its floor. It is an absolute constraint.
If the cheapest in-stock competitor drops below your floor, PriceSpy holds your price at the floor and flags the situation so you have full visibility. But it does not follow them down. You know what is happening. You stay at your floor. If a competitor is genuinely pricing below sustainable levels, that is their problem — not a market condition you need to match.
Floors are typically set based on one of these approaches:
- Cost plus minimum margin: your landed cost of goods plus a minimum acceptable gross margin percentage — for example, COGS + 15%. The floor moves if your costs change.
- Hard cost stop: floor set at landed cost. An absolute guarantee you never sell at a loss, regardless of market conditions.
- MAP compliance: for products with a manufacturer's Minimum Advertised Price requirement, the floor is set at MAP. This protects both your supplier relationship and your brand positioning.
- Brand value protection: for premium products where pricing below a certain threshold damages perceived value, floors are set above cost to maintain market positioning.
Floors are configured per product, per category, or as a blanket rule depending on your catalogue size and structure. For a store with 500 SKUs, category-level floors are common. For key margin products, individual SKU floors are set precisely.
The Upside Nobody Talks About: Automated Price Recovery
This is the part of dynamic pricing that genuinely surprises most store owners — and the part that makes the biggest difference to annual margin.
Floors stop you from going too low. But a properly configured pricing system also responds when competitive pressure reduces. When a competitor raises their price, goes out of stock, or exits the market, your price is no longer anchored to their last known position. PriceSpy lifts your price to match the new competitive reality — automatically, without any manual intervention.
This means the system works in both directions. It is not a one-way ratchet toward lower prices. It is a system that finds the highest defensible price in the current competitive environment, bounded by your floor at the bottom and your ceiling at the top.
The real example: a PriceSpy customer in the automotive parts category, monitoring a single air compressor SKU across 12 competitors. Three of the lowest-priced competitors went out of stock within the same fortnight. The remaining in-stock competitors were all priced above $200. PriceSpy lifted the store's price from $189 to $207 — still the most competitive in-stock option available, but $18 higher than before.
That $18 margin recovery held for nine days until competitor stock returned. At roughly 20 units per week, the store recovered an additional $360 in that window — without touching a single price manually. When competitors restocked, PriceSpy reanchored the price to the restored competitive reality.
Over a 12-month period, a well-configured pricing system typically makes as many upward price adjustments as downward ones. The net effect is not lower average prices — it is prices that are always as high as the market will support, and never lower than your floor. That combination is what protects and grows margin simultaneously.
Setting Your Price Floors With PriceSpy
Floor configuration is part of PriceSpy's onboarding process. You do not set floors yourself in a spreadsheet or navigate a configuration interface. The process works like this:
During onboarding, PriceSpy reviews your product catalogue alongside your cost data. For each SKU, or category where individual SKU data is not available, a recommended floor is proposed based on your cost of goods and your stated margin requirements. You review the proposed floors and approve them before any automated pricing begins. Nothing moves until you are satisfied with the configuration.
For MAP-protected products, floors are set at MAP by default and flagged for your review. For products without MAP constraints, floors are set at your specified minimum viable margin. For high-velocity, thin-margin products where moving volume matters more than protecting margin on individual units, floors can be set tighter — down to a hard cost stop if that is the right call for that category.
The floor review process is often valuable as a standalone exercise, independent of the pricing automation that follows. Many stores have not done a thorough product-by-product margin review in years. Seeing your actual cost-of-goods versus your current retail price across the full catalogue — with floors proposed against each one — frequently surfaces products that have been underpriced manually for a long time. Some stores discover they can raise prices on 10–15% of their catalogue before any competitor monitoring even begins.
Dynamic Pricing Works in Both Directions
The fear of racing to the bottom is based on how poorly configured systems behave — not how a properly managed one does. Price floors are the constraint that makes the difference. With them in place, no competitor action can drag your prices below the point where selling makes sense. Without them, you are relying on hope.
And the less-discussed half of the story is that the same system that protects your floor also recovers your margin when the market improves. When competitors raise prices, go out of stock, or exit the category, PriceSpy lifts your price automatically. You capture that margin without watching for it, without manual updates, and without the risk of leaving it on the table because nobody noticed the window had opened.
If automated pricing has felt too risky to try, the configuration process starts with floors — before a single price changes on your store. View the live demo to see how floors and ceilings appear in a real pricing dashboard, or get in touch and we will walk through your catalogue with you.
