I made a trip to BJ's as well today because I needed some meats, etc.
Here's what I picked up:
(1) 16ct Burger patties @ $15.69
-$3.50/1 BJ's Coupon
(1) Cheddar Cheese Shreds 3lbs (12 cups) @ $7.19
(1) Tyson Frozen Boneless Skinless Chicken Breasts w/ rib meat 10lbs @ $19.99
(1) 1% Milk @ $2.72
(1) Whole Milk @ $2.79
Total for Purchase= $44.88
I can't tell you exactly how much I saved, but I can give you a few cost comparisons of the prices for the bulk versus Publix.
1% Milk at Publix $3.29 - $2.72 = 57¢ savings
Whole Milk at Publix $3.29- $2.79 = 50¢ savings
Tyson Chicken 2lbs @ Publix currently on sale @ $5.99 (you can add a Publix coupon for $1/1 "limit one coupon per customer" bringing it to $4.99) which equals $2.49/ lb or $2.99/lb w/o coupon or BJ's price of $1.99/ lb. So, 10lbs @ Publix $28.95 - $19.99= $8.96 savings.
I love BJ's because they accept coupons, and you can stack a manufacturer's coupon with a BJ's coupon.
Everything listed above (except the milk) will probably last us a few months. We last bought these items about 4 months ago.
