Obviously bags

But what are some other things that you have 394034 of but still can not get enough and keep buying?
Mine:
-Barrettes, I buy SOOOO many and never get around to using half, but I can't get enough of them, such an addiction!
-Books - especially design books: art, interior design, and fashion, I need a bookshelf for them all because I've ran out of room on my nightstand bookshelves
