Walmart sells almost everything, not just food and usually in fairly large sizes. Winn Dixie (still walking distance) has less choice, but some great meat and fish for the BBQ with a good salad choice and great if you just want the odd thing as there is less likely to be a queue.

Taco Bell, right by Winn Dixie, also sells pizza hut pizza and just over H27 (it is walking distance, but I am not keen to walk over the main road) is Mac Donalds, checkers (burgers I think) and at the next lights is a kentucky. You can get chinese delivered
