Click here to sign up for a FREE sample of Rachael Ray's Nutrish Dog Food or download a coupon good for $3.50 off a 6.6 lb bag. This is a different offer than the one through Wal-Mart a few weeks back so if you signed up for that you can still sign up for this! Don't have a dog?? Go ahead and request the sample and then drop off at your local pet shelter - they will appreciate it! If you go the coupon route you could pair it with a $5/$25 or $10/$50 Petco coupon here and score a super good deal.
