Walmart+ is giving its members free Whoppers, discounts at Burger King

Walmart is giving its Walmart+ members free Whoppers from Burger King as the retailer looks to gain a leg up on rival program Amazon Prime.  

Walmart on Thursday announced the launch of its partnership with the burger chain, marking the first time the retailer has offered its members a dining benefit. 

Here's what now comes with Walmart+ membership: Beginning Thursday, members receive a 25% discount on every digital order they place at Burger King through the fast-food restaurant chain's app or website. Starting in September, members get a free Whopper once every three months, when they make any kind of purchase. Walmart+ members must link their memberships to a Burger King rewards account to access the discounts.
