Hurry! For a limited time on Groupon you can purchase a $10 Starbucks Card eGift for only $5.00! This is an invite-only offer but definitely worth checking to see if you got an invite. You’re looking for an email from the address noreply@r.groupon.com. You can use it at any participating Starbucks.
**Starbucks is a really popular store. So I expect Groupon to run out of them.
