This seems to be a big hit in California -I was at my 7/11 over the Thanksgiving Holiday, and 3 people in line had a bottle of wine or Champaign. The prices are very competitive with national grocery store chains. I think this will be a national hit.
I think the wine products are a good idea. It used to be that when I wanted a riesling I had to go to a large grocery to find it. Just last Friday I bought a bottle at 7-11 at a price very competitive with Safeway.
