I recently acquired John Vilismier's card collection with over 12,000 cards. Besides the usual casino slot cards and all sorts of hotel room key cards there are also a large number of Starbucks gift cards along with a few other gift cards.

I just finished listing close to 300 Starbucks cards on my Delcampe store and I still have one more box of Starbucks cards to go through.

If you want to take a look, here's a link to my store listings of just the Starbucks cards.

I should have the rest listed in the next few days.
