The previous posting is correct. Rebate offer ends 6/30/12 & must be postmarked by 7/15/12. However, for another free warmer (since this offer is ONE per household) I found a coupon booklet at Walmart w/a $3.00 coupon off one warmer. You can find this ina plastic wrapped limited edition of Febreze fabric freshener, Cranberry & Frost Scent). The warmer is $2.49.

Profit: Free Warmer plus .51 in your pocket. Can't beat that!
