Where are the batman roll ups in millsberry

There are two in the post office and the Clothing store.There are two in the arcade. One in the Grocery store. One in Peterson's Construction. Peabody Park. The Community Center. One in the Furniture shop. One at Tricks, Toys & Games. I believe there is also one at the Westridge Crater. I am missing only one, so there might bo more than one sometimes in a shop, I'm not positive.
