Price you paid - inflation

First of all, thank you for the fantastic work you do on this site. This is such a valuable tool and really adds a lot of fun and satisfaction to collecting.

With inflation how it is, I feel it would be useful to have the option to add the year purchased to each game, and to then allow users to toggle between original price they paid vs that price adjusted for inflation. It may look like a particular game has skyrocketed in value, but if it's something that was bought even 3 years ago adjust ing purchase price for inflation may show the user that what they paid back then is still in line with market rate. Or in the flip side that the true value of a game really has risen since they bought it.
