1. Items whose brand absolutely don't matter so long as they work as intended (e.g., books, home goods like hangers).
2. Home goods it wouldn't be worthwhile to knock off (e.g., KIND bars, toilet paper).
3. Smaller brands whose market share and item appeal are not worth cloning (e.g., a mechanical keyboard breadboard kit).
4. Things I'd order from banggood /aliexpress anyway, that Amazon will get to me faster (e.g., some diodes).
For everything else, I'd rather get it at a local store or order it from Target/Best Buy/Whoever than risk the Amazon purchase.
