I am looking to sell my legitimate accounts with
1000$ AWS Credit balance expiring December 31 2020. The running rate for AWS credits seems to be about 40% of their value, so I'd like
half of that, or 200$ 100$, for each account which is negotiable. Up to 10 are for sale. You will be able to change email and password freely once the account is in your possession.
You can use AWS services directly on these accounts, or create a billing organization with it and have your primary accounts join it. The processes will therefore stay on your main accounts while the bills go straight to this account with 1000$ credits.
Example:

These credits can be spent on any of the following AWS services:
AWS Budgets

AWS Config
AWS Data Pipeline
AWS Data Transfer
