I don't use a purse, usually, although I do have a few. If I do carry a bag, it's so that I can have a book with me. Other than that, though, I typically carry my driver's license and debit card in my back pocket or just a little wallet. Now that we have Clara, though, I do carry a small diaper bag and put my wallet in that. I think the most I'd ever spend on a bag is $50. The most I've spent so far is about $35 and it was one my friend made and sold on Etsy.
