Avguygeorge - I guess you must mean you won't be buying anything from anywhere except the good ol' USA. Because the hold-ups are caused by US immigrations, not Canada's.
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.
