I wouldn't get a Walmart battery, sometimes things can be too cheap. If I checked it right, you need an ETX14L, number used by a variety of battery brands, but all of them are probably made by East Penn. Deka, Big Crank, and Napa Power Sport all seem to be the same battery. Here's some links to those:

And this place sells them so cheap I'd be suspicious of getting the real thing/same quality as the others:

I'd want to verify that part number actually is what you need, but it kept coming up when I checked for 883 batteries at a few different places.
