Shopaholic? Me?

Supredrug are selling Fake Bake. It is meant to be a really good fake tan alternative. Not quite sure how it works, but any hints and tips will be appreciated. It will be nice to not look white and pasty as always but have a nice glowing complexion. So far I have heard loads of good things about fake bake but if anyone has actually used it and can comment, I would really appreciate it. Thanks.
