I'm sure you've checked out the PGEsaver coupons by now, right? Right!?!
Amidst the awesome coupons that load directly to your Kroger card, you will find "$5 off any Febreze Noticables Starter Kit." If you got the P&G insert in the September 28th paper, you have a paper coupon that states the same thing.
You can use them together! The Febreze Noticables run from $6.99 to $7.49, so you will profit $2.51-$3.01. I had to hunt for the $6.99 one--it was on a holiday display, not inline with the other air fresheners.
Be sure to purchase some other items to eat up your overage, as you cannot get money back from the transaction.
