Shipping quote problem with eCart6 and USPS
Shipping information is being sent to PayPal and I'm getting it back with the correct USPS quote; however, when a customer adds the additional four numbers to a US zip code (IE: 5 digit ZIP"-XXXX" *the Xs), nothing comes back. I end up with free shipping, which I definitely don't want. Is this a typical glitch with the USPS or is it something needing work in my checkout? Perhaps it could be coded to only return the first five to USPS on US addresses?
BTW: This is also occurring during a normal cc transaction, not just with PayPal.
BTW#2: I'm having the same problem with Canada. It's not returning a value either. All other international countries (though I didn't check every single one) seem to be fine. Any zip in Canada returns nothing.
