Mostly Ben Franklin's and Howard's for off the shelf purchases. I believe my mom did most of her Christmas shopping through Sears. We had a catalog-only store in town.
Wal-Mart came to town when I was 9. So some of my late toy purchases like Super Powers, GI Joe RAH and Transformers came from there as well.
When we ventured out of town I sometimes found things at Hecks and Hills.
