Looks like Amex is bringing us some good offers again. With this Amex Offer you can get a 1X $45 statement credit by using your enrolled Card to spend $45+ in a single transaction in-Club on a new Sam’s Club Membership at any Sam’s Club location in the 50 U.S. states by 9/30/16. The offer is valid on new memberships only.

Not valid on membership renewals, but you can get the credit even if you’ve previously had a membership. Since you only get a $45 credit, you would only get the Savings, or Business membership for free. If you’re going for Plus which costs $100, you’ll just get $45 back.
The offer is targeted but I see it in a few cards (OBC, PRG, Personal SPG).
Terms
Enrollment is limited. Valid only on a new Sam’s Club Membership (Savings, Business or Plus) purchased in-Club at a Sam’s Club location in the 50 U.S. states and not valid on memberships purchased online or by phone. Not valid on membership renewals, upgrades, add-ons or additional membership or any purchase of Sam’s Club Gift of Membership or Prepaid Sam’s Savings Membership. Must add offer to Card and use same Card to redeem. Limit 1 statement credit per American Express® online account. Statement credit will appear on your billing statement within 90 days after 9/30/2016, provided that American Express receives information from the merchant about your qualifying purchase. Statement credit may be reversed if qualifying purchase is returned/cancelled. If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the statement credit. For example, your transaction will not qualify if it is not made directly with the merchant. In addition, in most cases, you will not receive the statement credit if your transaction is made with an electronic wallet or through a third party. By adding an offer to a Card, you agree that American Express may send you communications about the offer. Sam’s Club is not a sponsor of this promotion. POID: CC1C:0001
