This is an AMAZINGLY generous giveaway with MAC and Benefit products along with other things too. The link to Andrée's blog is here and the post about her 100 follower giveaway is here. Her blog is great too, with loads of tips and photos to lovely make up looks so be sure to have a look even if you don't enter.
I think this is a great idea and as I've mentioned before I'm going to do one when I hit 100, so keep tuned to that :)
Good luck guys!
