I didn’t see any mention of like them in the rules. Guessing it’s just the same as buying blizzard cash?
All I saw was Microsoft points and stuff.

Gotta use real life trade forums for that stuff, in the donor forum

Thank you

Taken from xbox forum/behavior rules
Update: as of Jan 29 2009
Trading xbox live subscription codes and Microsoft point codes is now permitted in the Donor Forum.

These codes still cannot be traded here! Attempting to trade them may result in warnings and suspensions, or worse.
Of course if you violate this rule and get scammed, d2jsp will not refund any loss.
