Is there a wal mart or similar store near this camp ground?

If you are making a left out of the campground go all the way up the hill. To the right is a dollar general store and a grocery store . Theres a Walmart on the other side in Heber ,that's about 40 minutes

No. There are a couple of local grocery stores nearby. There is also a Dollar General and a lumber/hardware store.

I don't recall seeing one
