They do not charge for the plastic bags in the bulk or produce section. With that county you never know.
I have purchased bags for $1 at the grocery stores that I use. If you have some panels around sew them to the bag, right over the store logo.
One store in the area has red ones. I gifted one with a red hat lady I embroidered.
I don't know about the rest of you but, when I use my own bags things are easier to carry AND they don't break before I get them to the house. Can goods in your own bags is so much easier. I do make sure my meat or frozen items are placed into a plastic sack before they go in my own bags.
