When you have finished that, go to your Control Center, and there you will find a printable coupon for $10 off a Glucerna shakes multipack. Don't forget to backspace and refresh your page to print a second coupon.
This week at CVS you get $2 ECB's when you buy $10 of Abbott Nutrition products. The Glucerna shakes qualify for this. They cost $10.49 per pack. So, buy a pack of shakes for $10.49, and use your $10 off coupon. Pay $.49 and receive $2 in ECB's.
To make the deal even better, you can send in for a rebate at Caregiver's Marketplace. You must buy at least 5 packs, and they will give you $1 cash back for each pack.
