Free Prevacid 24HR 28 ct with coupon and mail-in rebate
The Prevacid 24HR 28 count rebate offer just started on September 18th. You'll have until November 18th to take advantage of the offer too, so there's lots of time to find a good price.
Note: This rebate offer makes the item free after coupon and rebate. So if you purchase the product without using the $4 coupon, you'll only get the purchase price minus the $4 coupon back, which won't make it free.
