Hi all,

Back in my DVD days, I always noticed that the original cardboard snapper cases from Warner Bros always contained these proof of purchase tabs on the inside spine.

To my eyes, it looks like something you would take out and keep. Then maybe at some point Warner Bros offered some items for sale and the price would obviously be a set amount of these tabs.

I only ask because I never heard of them being used for anything, including some kind of mail in purchase. That may be because I live in the UK and was importing US DVDs.

Did any of you guys know anything about these, or maybe even used them yourself?
