Where Does One Start with selling online?

Hi to all,
OK, now I have done ok on ebay. I joined SaleHoo and have found some sites of intrest. I have read what seems like thousands of sites, here and have found some that do not require resallers permits, monthly fee's, memberships, etc.
So do I cut and paste all of the information into the ebay store listing, for example, of an item I found? I guess i'm just not sure on how to use some of the web sites i'm finding here, that are more like a plain ecommerce site.

Help Please !!!
Thank You :oops:

You'll first need to purchase the item from the supplier and then list out that item on eBay. If you want to get the product from drop shipper then you can first check out the availability of the product and if that will be available then you can list out that item.
