If you need it, Farm & Home Ace Hardware will most likely have it. From home and garden to auto to pets to crafts, they have it. Their prices are a bit higher than Home Depot, however, their service is outstanding. They will help you find just what you are looking for, even if you are not quite sure what it is.
My sister went in looking for wiper blades for her car. They helped her find the right kind that she needed and then went out in the parking lot and changed then for her - at no charge - in the middle of a typical Wisconsin winter. Talk about customer service.
