Thanks for the suggestion. I tried that and every way I can think of, and after order submission it continues to say that the address is unrecognized.
My UPS store’s address has no suite number, so in theory it should be easier. I’ve tried placing the box number on the address 1 line in several formats, as well as the second line in several formats. I’m wondering if gcc blacklisted this address or something. Simon online works, and I’m going to change my billing address for gcm to try with them (requires large orders to go to billing address.) Otherwise, I guess I’ll have rented a mailbox that won’t get much use for the 6 mos I purchased.
Theres really no way to try an address before renting either. It just goes through or errors out.
