Great deal when you join Birchbox

So, right now (I'm not sure how long it lasts), when you join Birchbox and use the code: SFBB100 you can get $20 in points to spend in the shop. So you can pay $10 to get a month's box and a $20 credit to use on anything in their store. It doesn't get better than that!
