Correct.

They're not refundable nor can be returned.

Even on a bought item and SE'd for a refund?

The money In the GC Itself, Is not refundable/redeemed for cash.

Items purchased against the GC Is a different thing altogether. In this case, It's the Item that's In question, not the card.

Yeah it's something bought with the GC, doing a simple SE hoping to get them to refund my in money not with a GC. Should be allowed I reckon.
