Buy Box win rate after 30 days on PriceLens
A repricer without a floor wins the box at a loss.
Competitors move daily
Yesterday’s price is today’s lost box, and nobody can watch thirty listings by hand.
Your floor is not a guess
Fees, shipping and payment costs decide where you must stop. Most tools do not model them.
Coverage decides the box too
Price is one input. Incomplete specifics keep you out of contention whatever you charge.
Before and after
A week of price checks
The same work, measured twice — today’s numbers against the same catalogue running on MergeKart.
Six tools, five hubs, nothing talking to anything else.
Every job feeds one record, and the marketplaces follow it.

No. The floor is computed from landed cost and live marketplace fees, and recomputed whenever either changes. A rule may close a competitor gap up to that floor and will not cross it.
Continuously, rather than on whichever day someone remembers to check a spreadsheet. Each change is logged with the price it replaced, so a move can always be traced back to the offer that triggered it.
The Buy Box is an Amazon mechanism, but the same problem — being the offer a marketplace chooses to show — applies on Walmart and in eBay’s Best Offer dynamics. PriceLens repositions across the channels you connect.
Yes. Fees, competition and margin differ per channel, so floors and rules are held per channel against the same underlying product record.
Bring twenty listings and we will show you the gap.
Dry-run first: you will see every move the rules would make before anything changes.
