So here's an update for anyone who cares.
As I noted in my previous post, I checked the online tracking last night to find it saying "The commercial invoice is missing and is required for export. Released by clearing agency Now in-transit for delivery". I was rather confused by this as everyone I had talked to up to this point told me it wouldn't be going anywhere until I submitted a commercial invoice. So I called UPS this morning and asked them what this meant. The lady I spoke with was mind boggled by the fact that I needed a commercial invoice, yet it was sent out today to go through US customs and she was insistent on the fact that it wouldn't go through US customs without the commercial invoice. I'm like, okay, whatever, I'll just fax you guys this form so I can get this crap over with and get the package moving. I was planning to go out and fax it tomorrow morning, but I checked my online tracking earlier this afternoon and to my surprise the package cleared US Customs this morning and is now sitting in New York State.
I called UPS after I saw this and kinda ranted to them about the fact that it cleared US customs without the invoice. They ended up transferring me to four different people in four different departments to try and give me an explanation, which ultimately nobody could. I'm not complaining, but it would really be nice if UPS actually knew what they are talking about.
