(apologies if this is a redundant question, but I couldn't find it after browsing awhile...)
I am thinking about building an application that would essentially just use e-junkie as a simple/secure payment processor. My internal website application would handle all of the inventory management, pricing, product listings, etc...
I'm curious if anyone has any suggestions for how we could have the web application:
1- Calculate the value,
2- Pass this information on to a product in the cart which allows users to name their own price.
I realize this is a somewhat strange question! The reason for it is that I'm trying to build an otherwise fairly simple ecommerce system with a few quirky functionality requirements (which seem to be just quirky enough to require extensive mods to something like e-junkie on its own)... but I would prefer to not try to handle the actual payment processing on our own servers, as this is not my area of expertise.
Any input would be much appreciated. Thanks for your time!
