Top 9+ BJ's Membership Benefits and Rules You May Not Know
1) You get a free household card.

Once you've signed up for a personal membership, you can get a free household card for someone else in your family. There's also the option to purchase up to three additional memberships under the primary account.
3) There's a money-back guarantee.

If your BJ's membership no longer works for you, you can get a refund at any time. This can be done at your local warehouse or by sending a letter to: BJ’s Wholesale Club, Inc., Attn: Membership, P.O. Box 9157, Marlborough, MA 01752.
4) Shoppers can stack coupons.

Unlike other stores, shoppers can use manufacturer coupons along with those from BJ's. But there's one thing to note from the retailer, though: "One (1) BJ's Coupon per offer can be combined with one (1) National Coupon on a single selling unit, and the total value of all coupons redeemed against a single selling unit may not exceed the BJ's retail value of the selling unit."
