Well, I probably would have bought that for the cool label as well.
Most Cabs are pretty good and are a safe bet.
In general, for an inexpensive sparkling wine, a Cava is always a good bet. For whites, anything German. For reds, Spanish wines are usually a good pick. Italian wines are kinda hit and miss IMHO. There are also many good wines from the PNW, Cali, Chili, Argentina and South Africa as well as Oz and New Zealand. Let's not forget France, from which we often find inexpensive wines that are quite good as well as some worthy only of being used to cook with. Contrary to what some think, a wine that's nothing you'd really care to drink will work just fine in cooking.
We have a large local retailer here that has a wine section larger than an entire typical Aldi store. They usually have some real deal wines, and we'll often buy a bottle to try and if it turns out to be something we like we'll then go back and buy a case or two.
Aldi also has a nice little wine selection at moderate prices.
