For a college student, direct yourself to the nearest Trader Joes. If you don't like the two buck chuck, there are lots of $5 bottle. Their own label is very drinkable and usually $5.
The best label I have ever found under $10 is McMannis,
McManis Family Vineyards. I have yet to find a wine that is a better value. However, unless you are near the central valley in California, you will have a very hard time finding it
