US shipping & Worldwide Shipping

[ace1000]

Hi,

 

I have OSC Online Merchant v2.2 (I think RC2A)

 

I need a one flat shipping rate for ($5) for USA and another rate ($10) for everywhere else.

 

 

QUESTIONS:

 

a. Is there a mod for my version that does that?

 

b. Is there a mod that's flexible enough to incorporate any changes in the future ?

 

c. Can it be done without any mod in the current OSC OM v2.2 ?

 

Thanks in advance.
