Wine shops in Tucson?

[zenduck]

My wife and I are going to be spending a couple of weeks at a guest ranch in southeastern Arizona that is a BYOB establishment. We'll be flying into Tucson and renting a car. Where can we go to get a mixed case or two of good, inexpensive wine (Italian, Spanish, Portuguese, Loire reds, whites, & bubbles)? It'd be nice to go someplace where the folks actually know something about wine (unlike Trader Joe's).
