(Expires 5/11) Get a Free Box Jiffy Blueberry Muffin Mix when you sign up or sign in to your SavingStar account. You can use this at any store you have linked to your SavingStar account. New to SavingStar? Here’s a quick breakdown of how it works. Sign up for an account (it’s free). Check the store list to see if your favorite stores are in their list (which is quite long). Most stores that have a “store card” (like CVS, Kroger, Price Chopper, Giant, Albertsons) are on the list. Link your store cards to SavingStar (all of them). To activate an offer, just click “I Want This!” before you make the purchase. When you swipe your store card during checkout, and fulfill the requirements of the purchase, your SavingStar account will be credited. Once you reach $5, you can let the balance ride, or cash out by having the money deposited into your bank account, PayPal or your Amazon account.
