New Donut Costs - The purest usury!

Every few months or so, we do the same thing over and over. Somebody complains about the price of donuts going up, then somebody says the developer of the game is in the US, so the USD price did not change. Somebody else tells the OP that it is related to currency forex rates, and then somebody blames Apple/Google, then somebody else blames EA for being greedy.
