Ok we love a box of wine and we do for a few reasons:
Longevity! The wines going to keep for ages. No need to chop an entire 3L cask in one go unless you want to.
Sustainability! Cheaper than glass and much cheaper to transport. Have a look at that price.
It's darn good! This is Barbera, Dolcetto and Grignolino. Fresh, fragrant and screaming for pizza.
