…Assuming you mean, cardboard box with foil bag of grape juice inside and spout on front.
Nothin’ wrong with buying wine by the box, if it’s a wooden box filled with a dozen bottles of Chateau Lafite. 
:desperately wishes for smiley with lip-smacking tasty-good expression:
practice your spitting…after 4-5 different tastes your palate is done. The rest is a waste so save yourself for a specific comparison…re-taste the wines WITH FOOD…several different meals…price is important…many good $8 bottles out there…You(and I) Can’t tell why a $500 bottle is worth that much…Action Comics #1 is worth Thousands of dollars but not to me it isn’t…give up cigarettes, snuff, chew, and gum.
