Isn’t that what any store is? What the store wants to push (based on what they think people will want). If you didn’t see anything you wanted it may just be that you are not the target market. That is true of many stores. The more specialized the narrower the target market. The Amazon stores seemed to stock a lot of what a general bookstore would stock with a few novelty items like in a gift store thrown in.
A store is proximity plus curation. Of all the 985 possible car stereos you could possibly buy they have 12 that will serve a variety of needs while filtering out useless inferior or poorly prices options rather than you having to evaluate the a much broader selection of options. It's likely that your interests and the stores are somewhat aligned. At the front end there is a bunch of overpriced candy, soda, and magazines. Therein your interests aren't aligned. All of it is terrible for you and terribly priced. The entire section is designed to manipulate and harm in a small fashion all the people it is dealing with hopefully fairly in the other section. Consider programming vs ads same difference.
A store that lacks any direction, curation, and empathy is more like the front end or ad space than the body of the store or programming. It is not that they are focused on what they want to sell you of course they are. It's that they have put less thought in what they would want to buy if they put themselves in your place. An algorithm is a shit way to stock a store.
Most big box retailers lease store space (by the sq ft) to OEMs now, instead of buying and distributing the goods themselves.
Much less liability for the retailer, and puts the onus for sales on the manufacturer. I would be surprised if Amazon didn't try to do that with their 4-star shops.
