In my local supermarket in Spain, they sell wine in a carton (like milk) for around 80 cents of an euro per litre. It is perfectly nice if you want to drink a glass with lunch, mix it with gaseosa in summer (like Sprite) or cook with it.

They also sell cava for less than 5 euros a bottle. It makes a roast chicken on Sunday appear somewhat more festive. The first time a colleague in the UK told me about fruity or orange taste in wine I was completely perplexed as to what he meant.
