Couldn't have been $5 in March 2020, as there is a picture in the link from 2019 of Mickey bars being $5.75. And I was there literally 4 days before the pandemic shut things down (Still have a bottle of Germ-X I bought in the WL gift shop while we waited for our bus
), they weren't $5/each. We went out of our way to order several rounds of Mickey bars on our cruise before we hit WDW because of the price in the parks. Either way, the price of food and beverages these days is bordering on ridiculous. We've done more cooking in our room over the past several years as a result. I see no end to that pattern, provided we go back anytime soon.
