I haven't really used this site personally, so I thought I'd do a quick check for you. They seem like a legit company and have been online for roughly 7 years. I was unable to find any negative reports on them.
They offer automated inventory management and formatted product information from a network of drop ship suppliers, as well as other services. Their registration is FREE, so you can actually try and have a look around to see if what they offer will suit your needs. If you do decide to use them they offer various packages priced around $25-$50/month.
Hope this helps somehow. :)
Is there anybody familiar with this site? Maybe you guys can share your experiences and help out a fellow member...
