Yes I do. I am currently set it up for a client. Unfortunately, it is in beta version and not live to show yet. As far as the plugin it needs tweaking just to work with Paypal, as well as a comparision to a typical oscommerce site. So with your bank gateway question, yes it can, but you will have to program your way through. Some things to know about first:
– There are currently no individual pages. I did not create ones, but instead created an extra field with hide/show for a long description.
– As far as SKU, discount, etc., you will have to add those in
– The transaction process is broken on 2.0, but there is a solution in the comment area for the plugin
– The plugin css needs to be completely tweaked. It is atrocious.
– The developer provides squat worth of help. There is not contact info in the plugin as a clue.
– There is no feature for recurring users, unless you tweak it. I currently added shipping fields to WP which are then routed to the checkout to see if you are registered.
All this said it needs a lot of tweaking. I am going to release an addendum to his plugin with all the tweaks in two weeks if people are interested- so they don’t have to go through the same garble that I had to go through ??
