I found the knives on a free-standing display in the card area. There are tearpad coupons next to them. The knives scan at $9.99 and the “Buy 3 cards” coupon makes them free.
We haven’t tried the knives yet, but they feel like they’re of decent quality. Hey, these are going to replace a worn-out set we got free-after-rebate at Menards, so I guess we’re not terribly picky either :)
