I am trying to combine as many checkout / registration pages as I possibly can to increase conversion.

Currently in the checkout process there is a shopping cart -> registration -> payment information -> Confirm details -> success.

Is there a way to combine the registration / payment information / confirm details page into one page? My items are virtual so delivery address is not really needed. I can get by with name / email / password for myaccount unless there is a credit card payment.

Are there any mods that do this?

Thanks

Mike
