Re: Variable Pricing - 'Name Your Price' modification
There may be an affordable way for a small merchant to have similar functionality with X-CART (without storing credit card information) that you might show to your client after speaking with BCSE about using Braintree and their vault capabilities - see this thread
. I've not seen anyone report on these forums about a successful implementation with Authorize.net CIM and X-Cart - but you can vote for an implementation of CIM with x-payments at ideas.x-cart.com.
