I hope none of you threw away your RedPlum coupon booklet that came in the mail yesterday. Inside there is a $4 off any Knox product coupon. You can use this to get packages of Knoxx gelatin for free! The 4 pouch boxes are definitely less than $4 (at least when I've gone to buy them). Your cashier may need to adjust down the coupon amount to the acual sale price.
I scored this morning by finding 10 more inserts in the garbage can by our apartment's mailboxes (yes, I do lower myself to digging through garbage cans sometimes :). I should be well stocked up on Knox gelatin by the end of this month for sure.
