This is for new TopCashBack members only. That being said, if you are a current member, TopCashBack does not limit you to one account per household and encourages you to sign up your spouse and other family members. Just remember to use your Tell-a-Friend link to get a $10 referral bonus!
First: Sign up with TopCashBack.
Next: Enter Sears in the search box and you will see "Up to $8.50". Click "Cashback".
After reviewing the details click "Get Cashback Now".
You must purchase a 3.5 bag of Beneful dry dog food priced at $6.29.
Do not add anything else to your cart or you won't get the $8.50 rebate. Choose store pick up to avoid shipping charges. Since Sears doesn't carry dog food, you will probably have the option to pick -up at your local Kmart.
