Hoping a JR expert may be able to clarify aspects of these tickets...

Suica &N'EX - are these only available at Narita until 8pm when JR shop closes? Any other way of getting them if plane is arriving after 8pm?

Seishun18 - can these be purchased at any station or only large stations. Are there any Lines they work particularly well on or expect very slow travel with these

3 day pass - site says overseas sales to November 20...does this mean they must be purchased before going to Japan for use in December? Or can you buy them once in Japan up to end of December when offer closes?

Thanks!
