Regarding those customers in Canada that experienced issues with the site today trying to order GID Greasebat, we are sorry. We currently use real time shipping options with the USPS to determine pricing for shipping. Due to the current Canada Post Office strike the USPS is not accepting any packages to Canada so I believe this is why they would not issue a shipping rate for your order and therefore it would not go through. We did receive international orders outside of Canada without a hitch. I am sorry for the inconvenience at this time. Please let me know if you experienced this issue and I will try to accomodate you on a future release.
