Buyapowa = WOW!

Heya,
I found out about buyapowa when reading through a new blog I found called Brush Up and Make-up (which you should totally take a look at by the way)
It is a great site which I can't believe that I haven't heard of it before.
The idea is based on a co-operative style way of shopping where the more people who commit to buy a certain product, the cheaper the product will cost each person.
There are some great deals on offer there. I'm so excited that at the moment there is an offer on Benefit's Confessions of a Concealaholic which I have had my eye on for a while. They also sell many ranges such as YSL, Nars, MAC and Nails Inc. and there is the possibility of saving huge amounts of money on the luxury bits and bobs you usually cannot afford.

Here is a photo of the Benefit gift set that I'm so taken with that is on offer on the website at the moment.
If it looks up your street too, then follow my personal url *here* to pick it up and also give me the chance to win a set myself.

Is buyapowa a site that you use? What do you think of the idea? Would you ever use a co-operative based shopping site?
