Re: Variable Pricing - 'Name Your Price' modification
I don't think you can access that part of the forum until you actually purchase an XC license.
As for the price question - yes it can be done. Some part of it (like enter your price functionality) already exists under certain conditions. Hiding price or enter price until customer logs in also can be done. Storing CC info is a big NO-NO, even though XC supports it out of the box
