What is the enhancement in mind? How should it look and feel?
Adding Vault support so that we can purchase the packages in-game using in-game money thru vault instead of just DonationPoints
Please provide any additional information below.

There's two ways to go about this... either DonationPoints implements the vault economy interface so DonationPoints is the economy transaction engine, or DonationPoints uses the vault interface to talk to whatever the installed economy plugin is (eg: iConomy).

Personally, I think it would be better to do the latter - but make it an option in the configuration to use vault or not.
