BJ's Club membership (basically) free
You can join BJ's Club basically for free: Pay only $15 for a Club membership and get $15 back after your first purchase of $45! Or: Pay $40 for a "Club+" membership, and get $40 back after your purchase of $120. The pass is valid for one year. BJ's is the only club store that accepts coupons, and you can use 1 manufacturer's coupon per item in a package, even if it's a multi-pack. They also issue their own coupons.
