Starbucks $5 gift card with VIA Ready Brew purchase

I received this info via e-mail from Starbucks today about a new gift card deal. Could make for a good stocking stuffer:

"Through December 21-22, customers that purchase any 12-pack of any Starbucks VIA® Ready Brew in Starbucks stores in the U.S. and Canada will also receive a free Starbucks card, preloaded with $5."
