Coupon Connections NW found this great $1/5 cans of Bumble Bee Tuna Coupon here. You can stack this coupon with the 3 Day Sale in-ad $1/4 Fred Meyer coupon to get 5 cans for 75¢! You will just be paying for the 5th can.
This is the price at my local store, which is often times a bit higher than other regional stores, so yours many be even cheaper!
