Cheap Gift Ideas For Friends?

Okay we all know that christmas is coming. i would like to buy some gifts for them. I have already made them a card. I have 4 friends which i am buying for. They are all female. I was thinking of getting them lip gloss (lip smackers) or something... I was originally going to get them all funky eyeliner colors BUT my friend Tara said she has enough, Natasha, Doesn't wear it, Channie, doesn't wear it, and Kayla said she wanted silver. (Silver is hard to come across...she wants the perfect shade..) Yeah they are all 16, just to give you an age to think about... O it dosn't have to be make-up, And i will be buying this all at wal-mart.... Thanks for your help!
