This has had a significant impact on my buying habits as well. For luxury items, I tend to order them from a large department store chain, which is pricey, but more predictable quality, and for cheap knock offs, I just go to the source and get them from AliExpress for 1/3 the price they are on Amazon. Nowadays, you see almost the exact same stuff there without some rando brand I've never heard of attached to it.
