Suggestions?

I really want to sell some of my make up away because i don't use it anymore and i don't want it to go to waste.. For example, I brought the mac prep + prime and i only used it like twice in small amounted and i never used it again.. and i don't want it to go to waste so I'm thinking of having a blog sale but then again.. lol i don't think many people read my blog so.. i don't know. Any suggestions that you guys have will be great =]
