digitalFAQ.com Forums [Archives] - How to get shipping costs and pass to Paypal????

I need html code that gets UPS or USPS shipping costs and passes it
to Paypal. Paypal under Mechant Tools listed several 3rd-party
software products, but none seemed to be able to pass the final
shipping costs to paypal. I had to break the link and hard code
results to get this into a paypal <form> to have it available to
finish credit card processing. Has anyone found a solution (easy I hope)
to do this. This website is not Ebay, which has a built calculator for
shipping. This is a single item that weights 2.3 lbs with shipping box
in standard dimensions, $50 insurance, and nothing else. I tried
ActionInc. (trial version) and ShipScript (trial) which I couldn't figure
how to return to my webpage with the shipping price and sent this to
Paypal.

Thanks
