Does Walmart operate outside the US? Because Amazon is pretty much everywhere around the world. If Amazon were to die tomorrow, I'd have a real problem getting a lot of equipment for various projects, especially PC hardware, in a timely manner. As much as I hate how things have gone downhill lately, it doesn't seem to be as bad (yet) over here in Europe with getting fake items. The main issue I see here, is that there's been a huge influx of cheap Chinese items which flood out all the known brands that I usually buy from, making it hard to find actual quality items. Prime is also still 69€/year. And they offer delivery to their own containers which you can unlock with a barcode on your phone to get your package 24/7, avoiding house delivery altogether, which is a huge reason why I still use them as opposed to competition, since where I live in is a real pain to find and often delivery people just give up trying to find me and just send the items back, or drop it at some shop at the end of their shift, which is often at the opposite side of the city.
In fact it seems most of the issues I see people complaining about on HN are US-centric issues? Perhaps all this brand-hijacking is happening over there because of the market size and thus pay-off to do the "dirty" work?
