It will be much better if was developed some plugin or aplication that allow us to introduce the code provided by the payment system/company. Most of them provide a script to be included at any site or blog, but tha Classipress as developed, I have no adea where to include the script.
If the devepment team include an optional page that we can set up to redirect tha payment comand to there, and in this page we could include anyone payment script provided bya tha payment site.
This is very important specially for the non English spoking coutries.
Please consider something similar to this.
