changing product price with modifiers

["Andrey Buikis" <buikis@ftbcc.it>]

Hi all,
I am making store for selling shirts on-line, I am just starting to use
minivend but dont have
enough expirience. I have one problem, when user choose a shirt from
catalogs he can add
some extras (like initials, color of buttons, collar with double button
etc.). Any ideas how I can calculate price of shirt with these extras (for
example item-price + 2USD if user choose to add initials etc.)

thanks
