A friend of mine was about to be scammed by a bunch of pseudo-programers that intended to sell him a opensource shopping cart as if it was developed by them. Luckly he was smart enough to ask his geek friends first.
Now I'm committed to help him with this endeavor. But to be honest Im more into custom software development that into implementing existing solutions so this totally out of my expertise (comfort zone).
Can some one recommend me a Java or PHP opensource e-commerce solution (Please exclude any Ruby stuff... don't ask why)? Please tray to explain why do you think its the best option as detailed as possible.
Thanks a lot in advance, people!!
