Replying to an older thread... but still, it pertains, in 2013/2014.
I bought and received a quad (via ebay) from the UK in June of last year. It was folded and shipped in a sturdy 13.5 x 13.5 inch, sturdy, flapped cardboard mailer.
It got here in exactly One week (Monday - Monday). I paid the equivalent of $8.75 USD shipping (the sticker indicated it was sent Small Parcel service, via Royal Mail).
It arrived with no problem .... and was in the same condition as sent.
