I have literally never seen this but jack in the box is not a thing near me so likely pretty different area. All the same its easy to see why. One thing I have mentioned in inflation talks is how much the cheapest most base things have went up and soda is one of my poster children. Can still get 99 cents but only as a super loss leader which before was like 69 cents. buck 25 or buck 50 is still basic loss leader. 2 for five is a basic sale and they are 3 bucks not on sale. So it definitely doubled. Previously the cups cost more than the soda but I think that is changing.
