Until 8/1, Walgreens has the single bottles of Starbucks Frappucino's for $1.25 each after an in-ad coupon. You can get them for $0.25 each if you use the $1 coupon here (IE link) or here (FF link). And if you buy them today, 7/31, and use the 15%/20% off coupon you should be able to get them for a mere 6 cents!
Just be sure to give the cashier the 15% off coupon first, then the manufacturer's coupon and then the in-ad coupon so this rings up correctly.
This sounds like a yummy deal! I love this stuff and of course I always enjoy a cheap treat.
Thanks Common Sense With Money!
