What are some free things I can get at the mall? (a.k.a. a straw, fork cotton ball, etc.)?

I want to do a "Mall Scavenger Hunt" as part of my birthday party, but I don't want it to cost like $100 per person. I was thinking it would be fun if some things we could buy, (lip gloss, nail polish etc.) and some thing would be free, like a straw from starbucks, a cotton ball from a makeup store, or a brochure from a Verizon Booth. Does anyone have any ideas of what else we could "collect"? Thanks!
