I'm sorry I am a beginner and I have some questions about shipping & USPS:
1. I want to offer a free shipping in USA and $7 shipping cost for international . I do not want to send to Africa& Brazil but other then this two place I want to ship be able to ship anywhere else . How do i do that?
2. I just registered to USPS Web Tool and I got my user name a password. What I'm supposed to do next?
a little confused.
Sounds like you want to do "Zones"
Admin->Modules->Shipping->Zone Rates
in the first zone put just US and then in table enter *:0 (* for all, and 0 for shipping price)
in the 2nd zone put all the other countries and then in the table enter *:7.00
USPS Web Tools is needed for calculating rates based on USPS rates
