I was in Sainsburys earlier and they had all of their Skin a Therapy Self tan range reduced, some to about £5, but some to 50p, down from about £10-£15 per product.
I grabbed a few of the mousse and dry mist spray for pale skin, at that price I thought it worth the risk!
I've since found a review online which suggests it is quite good.
Just thought I'd share for anyone that wants to tan on a budget
