Walmart does pick and pack orders and supposedly will bring them to you, but I ended my Walmart Plus membership over the fact no one at the store picked up when like 5 cars were waiting for their orders. I wound up going inside and spoke to 3 different employees, none of whom apologized for the serious misstep.

A lot of walmarts don't even have any cachiers available, so if you won't do self checkout, you're SOL. I don't do self-checkout because I have a job, thank you, and I'm not taking one from a minimum wage employee
