Have you played Kroger's Instant Win Game?
It is very easy. Just make sure you have signed up on Kroger.com and play!!!
Play once a day
Each time you play you are entered in the Grand Sweepstakes
Win 2 items (I have heard of people winning $5 off next purchase, free CPK pizza, free coffee)
Even after you have won two items you can continue to play to be entered in the Grand Sweepstakes.
