Ok I made the big leap and failed BIG time

I had/have an on line shop and it's rubbish

I have an EKM power systems shop software is great but the £22 amonth for me and the lack of results it has to go..

and the world pay I think I have spent about £600 and got nothing back, which is my own fault I tell a lie I have a had a few sales where they just phone me up.. about £300-350

So I bought some software for a shopping cart and the back up from this one man band of software writers is great I feel I am getting some where and the set up is very cheap and it's only because it's new that it is cheap. It's nice and basic and flows well.

So I am looking to use Paypal as it's cheaper than world pay for payment. Then later on if and when sales rise I would look to go back to worldpay or who ever to get a better rate etc etc..

So what's the best way to do this, just put a small number of items ( that you know you supply in quick time ) out on the shop or put a number of things up and go for it.. ( would rather go steady than full on this time )

Any pointers and or pit falls to look out for ;-)
