That's what I thought for Walmart+, but here I am 3 months into a free membership having used it once. Nearly all items I've compared are more expensive than Amazon and more expensive than in store. The nail in the coffin is their search is awful and half the items don't qualify for the shipping benefits you're paying for! They're more than making their money back because people easily miss $1-2 differentials on essentials that add up to $40 on your grocery bill.
