I am currently not buying anything. I can replace staples, which include ColorStay foundation (which I bought 2 months ago, it'll last me a year), Voluminous mascara, and face powder. I ran out of mascara last month so I bought one for $7 at WalMart. I am not set to run out of any staples, so I won't be buying anything this month.
Other than that, I'm on a strict budget and I'm not buying anything. I inventoried my makeup, and honestly, I have one of pretty much every color (thanks to my Coastal Scents palette) and I have a really great selection of makeup, thanks to some clever buys in the past from Specktra-ites thinning their stashes. So I'm concentrating on saving every penny I can for now.
It's actually wonderful to come here and read about the stuff you guys buy --- I get a lot of vicarious joy from it
