Can I pay for something at one Wal-Mart and have it pick up for another Wal-Mart

Yes you just have to tell them what one if its online then you put the walmart you want to pick it up at as the primary Walmart

Specifically what some people are saying, you have to order online from the website and chose which store you’d like it sent to. The Walmart here in Marion doesn’t tend to ship store to store.

Yes.... Just let them know which Walmart you want it sent to

Best thing to do is call the Walmart in question

I've done that online several times. I ordered something for my sister and had it sent to her store to avoid the shipping charges but you have to make sure you put the other person in as able to pick up the products you ordered

I'm pretty sure you can. You can ask at the service desk to be sure.

Ni idea

It depends on what it is. If its a large item, maybe. You would have to call the 1-800 number.
