I order my on Oct 26th and they arrived today 10 days. No you don't pay tax/or duties. It comes in a regular envelop. The tickets are in a sealed plastic selve showing the back of the tickets. Just verify the details ie amount of days, hopper, and confirm the adult and child.
Mine were good!
I paid all in $797.85usd for 2 adult 10 passes with hopper and 1 child 10 day hopper. The price on the disney site was $822.18.
It was also nice to see the bill come in on the credit card at $773.24 cad because of the strong exchange rate!
go to mousesavers and register for their monthly news letter. Do it by the 15th and it will give you a further discount.
Hope this helps!
5 weeks to go!!!
