I know there are 3rd party extensions for this but i prefer the default OPC and would just like to reduce the number of steps.
Ultimately i would like to combine the Shipping Address and Shipping Method into one step and if possible do the same with the Payment Method and Order Review steps.
Any help on how i can achieve this would be greatly appreciated.
Its worth mentioning a very similiar question was asked here CE 1.9.2 - Onepage checkout - merge shipping address and method into one step although when i followed the instructions i was unable to proceed past the billing step so i'm assuming something is missing.
