Please use a fresh AWS account to avoid any issues. The codes are generated by AWS in batches (events) and only 2 from each event can be used on each account. If you have purchased codes from other people, bear in mind that my event could be the same as theirs and the code will not be accepted in that case. Therefore, use a new AWS for the codes you purchase and you should have no issues at all.
The price per code will change based on demand and supply as these codes have become harder to come by. There is very limited stock (although I do add codes every few days). For any other questions or queries PM me. Feedback is appreciated.
