Once again thanks to both Satya and fudjj for the advice.
I am now in the process of deciding on which products to start listing.
They also sell on eBay, although not all items are advertised but when you put up one of their products at times their link will come up in the "other recommended" suppliers. The product will be shown from their site right above your listing. This makes it hard to sell against them since buyers can see it at wholesale price (through the advertised link) right in front of them.
