Hi folks.
My friend is an online retailer and he says that one of the largest problem that retailers face is the lack of methods to reach new buyers. He checked out a couple services and found Happy Retailer.
I think this is a very interesting idea to allow retailers upload inventory in one place and sell them simultaneously on Amazon, EBay, Bonanza, (copied from http://happyretailer.com/?from=ej) and will probably one day expand to e-junkie
If you are a retailer it might be interesting for you.
