“I used to work through supplier lists row by row in a spreadsheet. Now I drop the file in and it surfaces the ASINs worth a closer look, so my time goes to sourcing decisions instead of formulas.”
— Alex J. (Wholesale)How wholesale and online arbitrage sellers use the Gridwinner terminal to speed up their Keepa analysis, surface margins they were missing, and steer clear of listings they can't win.
“Before Gridwinner, checking a supplier list meant hours of manual Keepa work. Now I upload the file — even a large one — and get back a ranked, costed shortlist to work from. It changed how I spend my sourcing time.”David M. — Amazon wholesale seller
“I used to work through supplier lists row by row in a spreadsheet. Now I drop the file in and it surfaces the ASINs worth a closer look, so my time goes to sourcing decisions instead of formulas.”
— Alex J. (Wholesale)“What I lean on most is the Keepa read — rank history and BSR drops in one place. It hasn't replaced my own judgement, but it's a much faster first pass than opening every chart.”
— Sarah M. (Online Arbitrage)“The true-cost breakdown is the part my old sheet was missing. Once prep and inbound shipping are in there, a couple of 'winners' turned out to be break-even — which saved me from buying them.”
— Mike D. (FBA Seller)“Big files don't choke it. I can scroll a few thousand rows and filter without the tab locking up, which is more than I could say for how I worked before.”
— Jessica L. (Wholesale)“Seeing Buy Box and offer-count signals before I buy has kept me out of a few listings where Amazon or a crowd of sellers had it locked up.”
