I don't know how it is in a WallMart in the US but in a French Carrefour there can be a 20 meter long aisle dedicated to wines and spirituous, possibly both sides of the aisle.

That's a huge selection covering all types of wine for as little as a few euros. Price is not a predictor of anything, there are both good and bad wines all over the place.

Wine is truly a commodity in France. There are very few people paying 10€ a bottle unless you're talking Champagne, that's not considered a wine.

I am french. I know the supermarkets, and still I frequently buy bottles above 10€. My demographic is not small, there are just many people that can't afford storage space for bottles and don't want to buy entry-level wine.
