Once again, Starbucks is making summer afternoons a little cooler with its popular Treat Receipt promo. Through Tuesday, August 30, make a purchase in the morning (anytime before 2 p.m.), bring the receipt back the same day after 2 p.m. and get any Grande cold beverage (including Frappuccinos) for just $2.50. (The offer is open to all customers, not just Starbucks Rewards members.) Remember, you do not have to redeem your receipt at the same location at which you made the morning purchase — any participating location will honor the receipt. For the budget-conscious, there’s no minimum purchase requirement for the morning receipt, so consider buying a Frappuccino cookie straw for 95ยข or banana for $1 to keep your costs down. MHOTC Tip: If you’re buying a morning round of coffee for the office (or, at least, buying more than one item), pay for each item separately. Then, you’ll have more “treat receipts” to share with friends and family. Or treat yourself to two bargain beverages — one in the early afternoon and one late at night.
