Would you reconsider and be willing to spend just a little more?
Big House Red runs $18 a box, which works out to be $4.50/750ml. You can buy the same wine for $8 in a bottle. It is a kitchen sink blend and comes in at a reasonable 13.5% abv. It isn't complex, but it is very drinkable. We basically always have a box of this sitting around. I have to imagine it is better than any $3 wine in a bottle.
Bota Box is another decent brand. The malbec and chardonnay are two of their better products. $17 a box.
Black Box is another option, though slightly more expensive at around $22/box most places.
A box also keeps better than a bottle, which means you can have just a class or two if you want and not worry about leftovers (not that I frequently have leftovers)...
