I would have preferred having three different shipping variables; i) local buyers could arrange an in-person pick-up, overridding shipping on the paypal form; ii) domestic (Canada&U.S.) a flat charge of $4.00 iii) international a flat charge of $9 However, I have made several attempts at working this into paypal automatic calculator, and have had no luck. I would appreciate if anyone could explain how I could pass a "blank" shipping field into the paypal payment form (don't care if it contains the value 0.00), but it must be modifiable. Thanks a million

I just thought of another scenario; I would also be comfortable with a solution that has a drop-down menu that had the following variables:

Select from one of the following:
-Free (Local Pick-up Only)
-$4.00 (U.S. & Canada Only)
-$9.00 (International)
