I have a minor USPS Module problem...
Seems that when a customer chooses First Class Mail as a shipping option, it is only priced correctly for orders under 13 ounces. If it is over 13 ounces, the post office bumps it up to Priority Mail and the cost is doubled (at my expense) Is there any way to fix this?
If not, how does the Handling attribute work for the USPS module? How can I add a flat handling fee to all packages...say 5%? I entered 5 in the box, but it seems to just add $5 to the shipping cost.
Thanks in advance for any insight into my situation!
