2nd card is free for personal members
Whether you purchase the Sam's Savings or the Sam's Plus membership, either one comes with a free complimentary household card. If you choose to open an membership for a business, you can add additional cards (called add-ons), of which each comes with an additional complementary as well. The add-ons, however, are not free.
You can get a second card on your account for free, I don't know about more than that.
May be a fee
