For me the ProStores are the worst way to reach your target market. IMO of course but it just doesn't make good business sense.
You see, you can setup your own store on almost any website for free. There's places like Link hidden: Login to view
and so forth that do everything for free.
And then you can line your products on these special free sites, add up your store....and just continually send the traffic to all of them.
It even gave me an idea too on how to expand.....Wow I love being able to tap into this, the creativity is always flowing!
That said and correctly, if you TRULY WANT an eBay store or a e-store/uBid store you're welcome to PAY for one and let it do its job.
Its just creating one using a quick page generator is faster and its FREE.
