Hey guys, We are currently building our new open-source shopping cart via OpenCart and we're looking down the paths of trying to integrate our website with eBay, Amazon, Google, Half, etc. Now, we were perhaps looking into integrate our store via custom API or perhaps signing up for a service such as Channel Advisor, E-Seller Pro, etc. to help us do this. I cannot really find prices on their services anywhere and I'm not sure which service really is the best. That said, if you have any suggestions, inputs, etc. that would be amazing. Thank you and I look forward to the responses.
I’m actually gonna start working on something similar soon and be interested in members input on this as well. I was thinking of using magento thou. Any help and input will = +rep
