To celebrate Sam’s Club’s first-ever Super Bowl commercial, the company is now offering $8 memberships, in-store only. This deal saves you $37 on a full-year membership, which costs $45.

Act quickly, though, because the limited-time offer is only valid for new members until Monday, Feb. 21. The deal was originally set to expire on Thursday, Feb. 17, but was extended through the weekend by popular demand.

“We work hard to win our members’ loyalty every day with the strategy to treat them like VIPs, which you see reflected in our game day ad,” Ciara Anfield, Sam’s Club chief member officer, said in a press release.

“Our participation in this year’s game is giving us an opportunity to celebrate one of the many perks of being a Sam’s Club member while opening the door to invite others to be part of the club with a membership offer that’s hard to pass up.”
