The chinese owned dollar stores or mom & pop dollar stores have sets like this. They are in the kids or make up section. Plastic pop open top with squares of eye shadow,lip gloss/lipstick,blush with applicators etc.
Store names forgotten but crossroads are what is important,right? East Valley of course:
Dobson/Broadway- SW corner- discount food store next to the reptile store
Broadway/Extention- Go East til you get to the last plaza on left side- Dollar Store type
Family Dollar
Dobson/Main- if it is still there..SE side- 99cents store
University/Extention-SW next to Fry's
You can always try having each girl use the same make up and just have a bunch of applicators to use it with- each time they use it they can just throw it away and not use another- and the blush brushes come in sets too.
