I have a site with DT Donate and DT Register. Would like to see a Cart option for DT Donate that would integrate with the DT Register so that my customer's can register and donate with only one payment transaction.
We are now working on a plugin that will do this. It will be a DT Register plugin that allows for donations during registration and creates a record for it in DT Donate. Hopefully it will be available within a couple of weeks.
