If I put 6.00 in the handling fee in the USPS module, will that then change the cost of the shipping from say $20.00 without it to $26.00 with the addition of it?
Will that also apply to international packages?
Thanks.
Also. how can I test this without logging in as my own customer?
Handling Fees are added on top of the charges quoted for the shipping modules ... each has its own setting ...
You test by creating test accounts ... you have a domain, make up some test email accounts such as:
test@your_domain.com
test123@your_domain.com
test223@your_domain.com
test323@your_domain.com
