> Is this fundamentally different than Costco using sales data to choose which Kirkland products to launch/sell?

It's 100% different. Costco doesn't make any of the Kirkland brand products. Their suppliers do. And Costco usually only carries one brand of, say, batteries. They go to Duracell and say "We want to buy X Duracell batteries and Y Kirkland batteries from you over the next Z years". If Duracell doesn't want it, their next call is the same thing to Energizer.

Basically, Costco says to their suppliers "We want to give you X high margin sales and Y much lower margin sales." And you know that going in. And are ecstatic because all those sales would otherwise go to your competitor.

Amazon says "here's a flea market", then uses their security cameras to see what items are selling at everyone's stalls. The next day, the stalls of the people who run the flea market (right next to the front door) also have the best selling items. Oh, and their tables are infinite and maybe they also fuck with the listings on the map to make it harder to find that those items are also at your booth.
