Since I’m getting all old and remember days and prices from long ago, when big hair and awesome music was all the rage, and you had to have a licence to keep a dog, Imma constantly searching for roughly equivalent prices over the years.

Historical prices can be converted into equivalent present-day prices by using historical inflation rates.
