Problem: I bought an item from someone on here, and it was shipped from Canada (I live in Iowa). The tracking shows it was received at a facility in Chicago a week ago, then nothing shows up after that. That doesn't seem right. USPS says there's nothing they can do (even though my local post office guy says they should be able to contact the Chicago sorting facility). Apparently any investigation has to be started through the sender with Canada Post, but he tells me that they say they can only investigate if it was shipped to Canada, not internationally. What? So I have no choice but to sit and hope that it somehow makes its way out of Chicago, even though it hasn't been scanned in seven days? This is frustrating. Any advice? Just to be clear, I'm not upset with the seller - he's being as helpful as he can. I just don't know what to do -- it was a VERY expensive purchase.
