I'm having increasingly bad experiences on Amazon. The most obvious ones are common problems - the reviews can't be trusted, and they're no longer price leaders in many cases. But there are some new experiences I'm running into now. Today, for the first time ever, I was double-charged for the same order. Customer support claims I was only charged once and there's no way to upload them a screenshot of my card statement so that they can see what I'm seeing. To be clear, these are two real charges (not pending charges or temporary authorizations) for the same order.
