Paid to take Smart Balance out of the store lol

Kroger has a scan-right guarantee program running where you will get any item for free if it is under $5 and the tag doesn't match the item. Smart Balance milk was tagged $2.49 at my store. I used the $1.50 from today's insert. It rang up at $3.99 so I paid $2.50 for it after coupon, and was paid $4 cash to take it home with me. So basically they paid me $1.50 to take milk home. I am really paying close attention to my receipts!!!!
