Might as well, as much as I spend at this place anyway. YMMV on eligibility on your card.
Get one additional Membership Rewards point for every dollar spent on your eligible, enrolled amex card online at walmart.com by 12/31/17.
ENROLLMENT/ELIGIBLE CARDS: Must add offer to Card and use the same Card to redeem. Only U.S.-issued American Express® Cards that are enrolled in the Membership Rewards® program at the time of purchase are eligible. Corporate Cards and all prepaid card products are not eligible. Limit 1 enrolled Card per American Express Card online account. Offer is non-transferable. Your enrollment of an eligible American Express Card for this offer extends only to that Card. Your enrollment does not extend to any other Cards that may be linked to your account (such as Additional Cards). ELIGIBLE PURCHASES: Offer valid only on Walmart.com. Valid only on US website. Excludes online gift card reloads, corporate gift card purchases, phone orders, product care & tech support plans, Vudu purchases, and box subscriptions (such as but not limited to Babybox, and Beautybox). Excludes purchases on third party or affiliated websites linked with/from Walmart.com (such as but not limited to Walmart Grocery, Walmart Contacts, Walmart Checks, Walmart Photo Services, Walmart Stationary, and Walmart Moneygram). See merchant website for shipping policy. Some merchants may not ship to all areas. Purchases may fall outside of the offer period in some cases due to a delay in merchants submitting transactions to us or if the purchase date differs from the date you made the transaction (for example, the purchase date for online orders may be the shipping date). If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the additional points. For example, your transaction will not qualify if it is not made directly with the merchant. In addition, in most cases, you may not receive the additional Membership Rewards points if your transaction is made with an electronic wallet or through a third party. EARNING POINTS: You will receive 1 additional Membership Rewards point per dollar spent using your enrolled American Express Card in accordance with the terms of this offer. These additional points are in addition to any points you would normally receive for purchases on your Card under the terms of the Membership Rewards program. When we calculate the additional points benefit for Amex EveryDay® Card products, points awarded under this offer will not be included. Additional points will be credited to your Membership Rewards program account within 90 days after charges appear on your billing statement. Terms and conditions for the Membership Rewards program apply. Visit membershiprewards.com/terms for more information. Participating partners and available rewards are subject to change without notice. The value of Membership Rewards points varies according to how you choose to use them.
