With any order over $15.99. Use code HOLIDAY2012 and get free shipping on any size order PLUS a free 16 oz. Rain Bath. I ordered a bar of facial soap for $1.99 + tax and it worked! 12/13/12 The code has been changed to free shipping and Rain Bath for orders OVER $15.99. Still a decent offer if you need just a few things that add up to $16 but not the bargain it was last night.
