Have you tried aliexpress? I need that kind of stuff all of the time for projects. If you are in the US the shipping takes some time but I have found aliexpress to be more reliable that amazon in the past 3 years, provided I don't need the object in 2 weeks.
I've gotten better at just finding other options. Amazon gets a LOT of business by keeping you logged in and not needing to do the drudgery of entering payment details. Once you log out? Suddenly they are not so attractive.
