I just had an order for cake toppers from someone in Canada. I messaged her to make sure that the 2-3 week production time plus shipping time to Canada would be okay. She said her wedding is June 30, so the production time is okay, but that it will take a month to get to Canada if I send it USPS, so she wants me to send it FedEx COD. I've never done this before, so I'm not entirely sure what it entails. Has anyone else shipped COD before?
