Hi, i was sending a small flashlight to the US, maybe about 200g. I brought it to the post office (i have never shipped to the US before), and the postal worker gave me a flat rate xpresspost USA envelope (one of the smaller ones), and mailed it. That was friday. I now realize that those envelopes are supposed to be only for documents and I never filled out a customs declaration form because the guy said it didnt need one. This seems weird to me that it doesn't need a customs declaration form. I realize maybe i should have mailed it expedited instead. The package has not left that post office all weekend... if i call Canada Post tomorrow first thing in the morning can it be sent back to me so i can resend it expedited? It has tracking and everything on it. Thanks but the envelope says documents only on it.
