FORUMOM
I found two versions of this deal with the same code but different info so YMMV, sorry. I've heard with their previous free shipping deals that the site will sometimes show shipping charges until checkout, so don't get discouraged if it looks like it's not working
Watch out if you're buying anything small e.g. mousepads or eye masks, as there are often better deals, and also with swimwear and leggings which often go 2for1
