I mean they don't have "inventory" in the dictionary definition of the word. I search for items, and they will sell or fulfill an order that I click on, but the results are a confusing list of pseudo-similar things.

It's just like searching the internet for a product, not like buying from a store.

It would be like if I went into Target, and rather than an organized collection of products, it was a flea market with real and knock-off items lumped together in big piles all around the floor. And then a bunch of helpful employees to get me checked out real fast when I made a decision.
