How long does USPS take to ship to Canada? « IBEROSTAR …I ordered a Nike ID product on August 29 and it was made and shipped to Florida in about 3 weeks, on September 20. On September 22, after it arrived in Florida, it was shipped to Canada via USPS, the cheapest ground shipping way. My Nike ID package still has not arrived, and when I log on to the tracking website, it only says that it was accepted in Florida. I’m getting really worried that USPS lost my order! Help!!
