They have a provenance problem. If you're okay with cheap plastic that may work acceptably for a while, it's great. But if you have a specific product or brand in mind, it's not a good choice. Real-world example: I have a device with sensitive optics, and the manufacturer recommends a specific brand of lens wipes to clean them. The wipes can be found in some stores, but the manufacturer directs customers to Amazon to buy them. That was good advice 5 years ago, but now the recommended Amazon listing is full of reviews saying that people received dry expired wipes, often loose in generic packaging. I won't risk an expensive lens by using a possibly-expired cleaning product that has been comingled with counterfeits. So I buy the wipes from local pharmacies or camera shops, even if it means an extra trip. These days, I have the same view for food, cosmetics, fire risks like chargers and batteries, etc. Today, there aren't many things that I do feel comfortable buying from "the everything store".
