Don't know if this is common knowledge or a new promo, but I bought a 12oz bag of Dark Sumatra roast in the grocery store last week and noticed this on the back: "Bring Us Your Empty Bag, We'll Give You Coffee". Basically, exchange the empty bag for a Tall brewed coffee at participating Starbucks. Expiration is 30 days after the "Best Before" date on the bag, which for mine is Sep, 2012. I got the bag on sale, so this amounts to a bit more savings. Log In
