Does walmart sell wine in NJ and PA?

Funny how the laws are different everywhere. Few weeks ago, when passing through Oklahoma, I stopped at Walmart to buy a box of wine for the camper. They sold beer, but no wine. I was told I had to go to a liquor store for that. Then you go to St. Louis, and they sell everything in Walgreens and the grocery stores. In Texas, we can buy beer and wine in grocery stores. But, we have to rely on our awesome liquor stores such as Spec's for anything harder.
