I went with my ecbs in hand to purchase the Coke deal earlier today. Coke products are 5 for $15, then get $5 in Extra Care Bucks back with one limit per Extra Care Card member. I purchased 5 Coke products and got the $5 ecbs on my receipt. Then I made a second purchase of 5 Coke products plus a filler item since I had $19 in ecbs. When I got the second receipt, I got another $5 ecbs!!! I am not sure what the limit is, so I may go back and get 5 more Coke products. I would be interested to know what the limit is. Sometimes there are 4!
