I've help a local karting company start a website. Not too bad.

http://www.tredwayspeedshop.com/TredwayStore

They htheirhier own accounts wtheirhier pricing "breaks". Is anyone building USPS and UPS modules that use the store owners true shipping accounts? They are just uncomfortable wtheirhier charged rates and actual rates being different.

I've seen ShipStation but UPS seems to be 'estimated' as well.

If no such modules existtheirse thier personal accounts do you have any suggestions or is the shipping mismatch adilemman dilema for E-stores?

Thanks for your replies,

Rob Jackson
