I like the Super Walmart. Definitely go with a list. And shop the pet food isle first (It is away from the groceries - near the pharmacy.) Then I usually go to the garden section if I need anything, then housewares, turn right at Electronics, I might then shop if I need clothing, then over to Dairy,(milk is all the way in the back) and then frozen foods, pop chips and canned goods, then fruits and vegetables. This is why one needs a list!!
Always bring my coupons and they will take internet coupons. Just be careful to read all the fine print before bringing them. They read them very carefully...
