$18,000 Extra Profit in 30 Days: How an Aviation Parts Seller Finally Made Repricing Work

They tried a different repricer once and turned it off. Here's what changed with Flashpricer, and why "we've already tried that" is usually a stale answer.

Most sellers who say "we tried a repricer once and it didn't do much" aren't wrong. They're just describing a different catalog than the one they have today.

That was the case for Eduardo Reed and his team at Gulf Coast Avionics, an aviation retailer selling pilot supplies on Amazon: handheld radios, kneeboard charts, field testers, mic muffs, headset bags. Niche category, complicated competition, and a product mix that had quietly changed underneath them.

Thirty days after turning Flashpricer on, they were roughly $18,000 more profitable than the month before.

Why they'd written off repricing

Gulf Coast Avionics had used a repricer years ago. At the time, most of what they sold was MAP restricted, so there was nowhere for a price to go. Their manager looked at it, saw almost no room to move, and shut it off. Fair call.

But catalogs drift. By the time we met Eduardo at the Prosper Show, the product mix had changed significantly. A lot more of what they were listing had real pricing range, real competition, and real buy box turnover. The old conclusion was still sitting there, though, which is what usually happens. Nobody re-runs the test.

They agreed to try it for 30 days, mostly to prove or disprove it.

The setup: one strategy, plus what they already knew

Nothing exotic here. They started with a single recommended strategy and then layered in their own category knowledge on top of it, which is the part most sellers skip.

Aviation parts don't behave like consumer electronics. Eduardo's team knows which items are commodity and which ones are effectively theirs, which competitors ship out of a real warehouse, and which SKUs move twice a quarter. That context got built into the strategy rather than left in someone's head.

Most of their catalog is merchant fulfilled. They do run FBA, but they lean FBM because the fees are lower, and that difference is exactly what gives them room to be more aggressive on price than a competitor paying FBA fees on the same item.

The result

In Eduardo's words:

"We did what was recommended. We started with a strategy. We also brought some of the knowledge about our industry to that strategy. And within a month we were able to see some results, over $18,000 in profit."

That's month one against a month with no repricer running. Their finance team ran the numbers, not us. The internal verdict was short: keep it on.

What comes after month one

Getting the strategy live is the easy part. The compounding happens when someone spends 20 minutes a week working the catalog in buckets. Here's the loop we walked Eduardo through, which works for any catalog over a couple hundred SKUs.

Start by filtering to listings assigned to a strategy and currently in stock. In Eduardo's account that took 215 items down to 137. Then add "not in the buy box." Now you're at 47 items, and you're looking at a real problem list instead of a spreadsheet.

Split that list two ways.

Items with sales in the last 30 days that aren't winning the buy box right now. Check whether the buy box is suppressed on the listing. If it is, that's a rules question, not a price question. If it isn't, look at your price against the target competitor, then check how many units they're holding and how fast they're promising delivery. If they can get it to the customer faster than you can, you have to beat them by more on price than you otherwise would. Delivery speed is a price input, and most sellers never look at it.

Items with no sales in the last 30 days. Sort those by stock, highest first. Fifty units sitting still is the most expensive thing in the account.

Then split each of those again by "at min price" versus "not at min price." If a listing is at its min, price isn't your lever anymore, and you're deciding whether the floor itself is wrong. Pull sales velocity over 7, 15, 30, and 90 days and look at estimated days of stock left. When that number comes back as something absurd like 555 days, the answer is usually yes, the floor is wrong.

If a listing isn't at its min and still isn't winning, the strategy is too soft. Duplicate the strategy you're already using, make one version sharper, and set different rules by competitor fulfillment type. If an FBA seller holds the buy box, a strategy that subtracts a flat 3% regardless of who's there is leaving room on the table. Push that to 4% or 5% against FBA while keeping the FBM rule tighter.

Two things make this fast enough to actually do every week. Every filter combination lives in the URL, so you can save views and share them with your team instead of rebuilding them. And once your filtered list is right, select all filtered, bulk update the strategy column, apply. Eduardo moved his entire FBM problem set to a new, more aggressive strategy in about a minute.

If you'd rather work in Excel than in the dashboard, the same filters are available in scheduled custom reports, delivered daily, weekly, or monthly.

Where they're headed

The target for month two is $22,000 to $25,000. That doesn't come from a better algorithm. It comes from the waterfall: a default strategy that catches new listings, and a handful of tighter strategies underneath it that items get sorted into based on velocity, ROI, and whether they're winning.

If you've tried a repricer before and shelved it, the honest question isn't whether repricers work. It's whether the catalog you tested on is the catalog you have now.
