I can order somethin on line and pick up at the store ?????

Yes, but check the availability of product in that particular store.

Here is a link to the 2750 West University location to check their inventory. If you would like to change locations there is an option to do so about 1/2 way down the page. https://www.walmart.com/store/4627/denton-tx/search
