You may also want to checkout Digikey. It’s more focused on discreet components, but they have a huge catalog of electronics that’s worth searching through, and pretty reasonable shipping.
Yeah, I've used Digikey for a few odds and ends too. I wish Amazon would just deal with their seller issues. Per-seller labels to at least track which seller's goods are counterfeit and/or problematic would be a good start. A big fat warning when refunds/returns aren't handled by Amazon would be another.
