I did a search and Walmart is not planning to charge for self-checkout.

Is Walmart charging for self-checkout?
No, Walmart is not charging a fee for self-checkout.
However, during times of limited self-checkout access, some Walmart locations are reserving self-checkout for their Spark delivery service drivers and for those with a Walmart+ subscription, Bohl said.
