You got it backward. According to the AWS Promotional Credit Terms & Conditions the codes are given to the end users only by Amazon. You can not receive a code from a third person and you can not give or sell a code to a third person. If you violate these Terms & Conditions the codes are void and Amazon can remove them anytime.

If you still don't get it, let me reiterate: each and every code that you obtained in any way from anyone other than Amazon is from unknown and illegitimate source and may be canceled.
