I've bought Chuck Shaw Cabernet before. It wasn't terrible, definitely good for the $3 it cost me. Keep in mind, at $3, your competitors in the "Red" category are Night Train, Mad Dogg (only the Red Grape flavor), Wild Irish Rose, and certain varieties of Cisco.
If I'd drank it without a price tag, I'd have assumed a $6-8 bottle, which is usually a decent table wine. Of course, I'm sure that the variety/vintage of Cabernet I had 3 years ago, the last time I bought it, is a lot different than what they sell right now.
