How to get override GetFinalPrice from plugin

yeah we tried what you suggested but didn't work.

Did you get a chance to write your own plugin for the same thing?

Will write it tonight UK time and let you know

Hello there,

Did you write the code and was that successful?

Nope, everything didn't go to plan.  Been unwell all weekend.  I have decided that for what I want, I need to create a new shipping plugin.

Hi,
I have same problem.
Is there any progress?

What is the problem, your service isn't getting called or you're still getting the circular reference error?

Hello,

I'm trying establish overriding GetFinalPrice method, but without any success. I'm using Nop 3.50. I create plugin with DependancyRegistrar and service which overriding one method from PriceCalculation but method is not called. I check and that new service is registered.

I create like example before, but with no success!!

Please if someone could help me. I uploaded plugin with source code in link >>

Thanks in advance

I already resolve Issue. The problem was in one another plugin, which also implement IPricaCalculationService so my plugin never been hited.

And example above works fine.

Thanks
