Are you sure that the price of wine has gone up? I don’t know for sure but a bottle of Charles Shaw was $1.99 a few years ago and I think it’s still $1.99. Admittedly I haven’t checked for awhile.
I can tell you that a 40 oz. Old English has gone up in the past few years; you used to be able to get one on occasion for 99 cents but now you’re looking at $1.69 minimum and that’s if you look.
In any event, inflation is real and it’s more than 2%.
