Groupon continues to offer a Sam's Club Savings 1-Year Membership bundled with a $10 Sam's Club Gift Card for $30. (This deal applies for new members only.) Assuming you'll use the gift card, that's tied with our mention from last week, a savings of $25, and the best outright price we could find.
Of note, Sam's Club offers its Savings 1-Year Membership bundled with a $25 Sam's Club Gift Card for $45. (The gift card will appear in-cart.)
