Starbucks is offering a $5 gift card via mail in rebate when you purchase 3 packages of Starbucks Coffee or VIA Ready Brew. Starbucks Store purchases are NOT eligible. The purchase also needs to be done in one transaction between 11-01-11 and 12-31-11.
The rebate can be submitted online or by mail. You can link to the form from here. Here is some of the fine print that I took from that site:
Excludes Starbucks VIA® Ready Brew 3-pack and Starbucks® K-Cup® portion packs
Offer valid on:
10, 11, 12 and 20 oz ground or whole bean Starbucks® coffee
6, 7, or 8 ct Starbucks VIA® Ready Brew
Or a combination of three (3) qualifying products
