Someone posted this on another board and I just ordered one. The promo only applies to the "essence" line and they only have pink and blue left, available at this price while supplies last. I think shipping was $7.95 and the covers are normally $32. It looks like the hooter hider covers. I googled it hoping it wasn't a scam and found it on several mommy deals type sites.
Here is the web site. You have to entire promo code onefree.
