Hello,
I am in the exact same situation. I am paying $50 a month for inventory source to do exactly this. I have recently asked them to create datafeeds based on the products on my website, they were not able to do so so far, and again I am paying them for this as well additional $10 per month, plus the sign up fee $15. I feel like going over there and slapping someone across the face because the only thing they are good at is taking their monthly payment. I am agravated and a little bit dissapointed that there is no system for zencart shopping cart users to do this on their own, manage their own product via pricelists provided by the suppliers, and for datafeed submitions. Anyone working on this? Anyone has any suggestions? Please! I cannot waste anymore time or money with this crappy inventory source company. I want to be able to do it on my own. Thanks!
