Are you able to drink it from a bag?
Of course, there's a lot of great non pretentious wine that comes in bags.
When I lived in France I used to get it around 60 liters at a time in 3l bag in boxes from the vallée de la Loire
Back in my home country Italy it's not as common but you can still get massive bottles (we call them "damigiana") from farmers at circa 2.5 euro per liter.
Excellent wine can be very cheap if produced in quantities, for some marketing reason here in the U.S. a lot of people have been fooled into thinking that wine has to be $25 per bottle or above to be drinkable.
We have many that think this way in Europe too, but they tend to be snobs rather than uninformed.
Here I get my wine at trader joes, and my favorites are trader joes Blanc De Blanc (a dry, sparkling wine from France that sells for $5.99 per bottle), an Italian Pinot Grigio again for $5.99 and a rotating cast of red Bordeaux for anywhere between $7.99 and $8.99
