For each Installment Plan you set up, a set up fee of 4% of your total purchase amount (after applying taxes, discounts, Walmart Reward Dollar redemptions, and shipping/delivery fees) will be charged to your Walmart Rewards Mastercard account on the posting date of the purchase. The set up fee is not refundable (including if an Installment Plan purchase is returned), unless you cancel the Installment Plan within 30 days of plan set up. From time to time, we may run promotional set up fee offers. Terms for these offers will be disclosed prior to your agreement to set up an Installment Plan.
