The only problem I had with delivery in December were packages sent out at the beginning of the month to the U.S. I had quite a few customers emailing about those but the ones I shipped later arrived quickly.
Actually I had far fewer customers contact me this year in that regard than I did last year.
December was my best month ever on eBay. Closing for that month is definitely out of the question.
(I also noticed that most of the last minute shoppers were men). ]:)
Why risk postal fraud when you can get them for HKD $13 ?
I noticed HK sellers add this stickers on more valuable orders and underdeclare it. This makes it fly through customs fast and is fairly safe against "loss".
I didn't think this affected me but now I have a standard lettermail envelope that has not arrived in the UK after two and half weeks. Usually UK shipments are as fast as local shipments...at worst national shipments.
