Walmart is partnering with Capital One to launch a new credit card program, which rolls on September 24, and includes both co-branded and private-label cards. The former, the Capital One Walmart Mastercard, includes 5% back on purchases made on Walmart.com or paid for in-store using Walmart Pay (the latter for the first 12 months.) The private label card, the Walmart Rewards Card, will offer those same perks, but is limited to being used only in Walmart stores and on Walmart.com.

After the 12-month introductory period, the co-branded Mastercard will drop to 2% on Walmart purchases in stores, instead of 5%. However, it will continue to offer 5% on Walmart.com purchases, including Walmart Grocery.
