Im just a customer myself. But I think the price varies on size.
I did a search with filters narrowing down the results to the following: Air mattress In store pickup at the two Walmarts in Nacogdoches only Sorted from lowest to highest price (There is some random camping and bedding related such as pumps and cots in between but keep scrolling and there's more mattresses) Here's the link, hope you find what you're looking for!! https://www.walmart.com/search/?cat_id=0&facet=pickup_and_delivery%3AFREE+Pickup+Today&grid=true&page=1&prg=mWeb&query=air+matress&sort=price_low&stores=163%2C4674
