I have got credits of various denominations like $40, $50, $100, $150, $250 etc. Many of them are stackable which means you can apply other codes of same type (or same event) in one particular account and obviously you can apply all types in one account as well. For "how many stackable" check their individual buy page (click shop link below and then you see it) for current status.
