Currently developing an online business and looking for a way to set up the shopping cart portion. We sell completely customized items to people. Using the options feature in the easycart, is it possible to include "upgrade" options? example would be like buying a car. You take your 1000 dollar base model, and on a drop down menu you select "power locks, add 50 dollars." in another section would be "upgrade from 2.5L to 3.5L engine, +1000 dollars", and in that same drop menu would be "downgrade to 2.0 L engine, -500 dollars." Obviously I'm making up the numbers, but I can't tell from watching the videos and reading the support forums if this is possible using this plugin. Any feedback would be great.
Thanks!
Thanks!
