Free Socks at Kroger

I live in the Central Ohio area so I have no idea if this is the same way at other Krogers. I did my shopping today and as I was heading out of the store a cart was filled with No Nonsense socks marked $1. I had a coupon from a few weeks ago in an insert and it was for $1 off of a No Nonsense product so they were free. It scanned just fine I just wish I had a few more coupons.
