That question seems absolutely alien to me. Surely you have alternatives in the US, don't you? Here in Germany I visit Geizhals, search for the product in question, sort by price and order from one of the countless shops that have the product in stock.

Maybe I'll end up on Amazon, maybe not - they all can deliver quite fast and they all have to adhere to european minium return policy standards. So the handling of returns isn't something most customers ever have to think about.

Just to give an example here's the price comparison for a current AMD CPU: https://geizhals.de/amd-ryzen-7-7700x-100-100000591wof-a2801...

Don't you have anything similar over there?
