Outside of AWS, you're looking at inflated prices, sometimes 5-10x for normal products, about half the inventory (if not more) filled with fake, low quality garbage from China, Prime 2 day deliveries that often take much longer and sometimes never arrive, and some of the worst (but also best, it's hit or miss) customer service I've ever seen. Fulfilled by Amazon doesn't do shit to address any of these problems. In fact, Amazon doesn't do shit to address any of these problems. You'd think it'd at least address the fake/crap goods problem. Nope. AWS itself seems to me to simply be an unfinished service that people are willing to pay vast amount of sums for the privilege of complaining about their AWS bill. Hell, it's so common, it's now happened twice in the show Silicon Valley (same AWS joke, two times) and too many times to count at every job I've ever been at that considered AWS. Outside of AWS, Amazon is not only catchable, for most products, there are already better alternatives.
