Sadly, I think that a lengthy hold-up is a real possibility. If memory serves, there was actually a closeout deal some years ago on a cd transport or player (want to say a Roksan model, but I'm not sure) where the stated reason for the pricing was that the goods had been held up in customs long enough to frustrate their originally intended distribution. I believe the merchandise ended up with Audio Advisor.
Held up in customs
I just purchased a CD player from a gentleman in Vancouver and had it shipped UPS Expedited 2 day. When the package got to the states it was placed on customs hold. When I spoke to someone at UPS they said it would take at least a couple of days and customs could do whatever they wanted to the package or simply keep it. I'm wondering if anyone out there has had any experiences with the Customs Service or FDA in regards to international shipments.
