Question about sideshow gift card with DVD

[Battletroll]

Usually the first 3 letters/ digits denote the promotion the GC belongs to. For example, Comic Con 2008 cards start with CC8 and the Catalog #10 card starts with CA2. So I would assume that if the DVD GCs each start with a different denotation, they count as separate promotions.

Does anyone know the expiration date for the Indy DVD gift card? I am moving things and I packed the set away without taking the giftcard out. It would save me some hassle digging it back out if someone knows. If it doesn't expire for awhile I'll leave it be for now. Thanks!
