ULPT Request Amazon sent 10 SD cards, only ordered 1. What should I do with the extra?

See, that's the problem. Amazon doesn't care at all since they do not pay for it. It's the vendor who is selling on Amazon. It is good that Amazon generally treats its customers well, but they do it at the expense of the vendors, but make it seem like they are the good guys. They are really just complicit. This happens with returns as well - If Amazon sells something of mine and it gets returned, it usually gets thrown out by Amazon (who actually charge me to throw it out), and they take the value of the item out of my account. When someone orders something of mine from Amazon to "borrow" it, basically I'm giving it away for free, and Amazon is charging me extra to deal with it - once again they make it seem like they are the heroes, but it's at the vendor's expense. There is a way to get higher valued stuff back instead of it being thrown out, but they will not ship to Canada (where I am). PLUS when this happens, you get a negative mark on your account and your sales go down. Technically, there is sometimes a way to get compensated, but from a practical perspective it doesn't usually happen.
