Starbucks Store cuts 15% off sitewide via coupon code "MSR15FA14". That's tied with our June mention as the best sitewide discount we've seen from Starbucks this year. (For further comparison, we saw up to 50% off sale items with an extra 10% off for new customers a week ago.) Shipping adds $4.95, but orders over $60 qualify for free shipping. Some exclusions may apply. Deal ends September 10.
