Hello,
Thank you for sharing your experience. We take reports of website errors very seriously, as our platform is specifically built to prevent the exact situation you are describing.
To clarify how our online system operates: we use a strict, live postal-code filtering system. Once a postal code is entered, the site automatically updates to display delivery availability. If an item cannot be shipped to your specific region via our freight partners, the system is designed to restrict the checkout process immediately, not at the very end of your transaction.
If you possess a screenshot showing an item marked as available for delivery to an out-of-zone address, we would genuinely like to see it. This would indicate a highly unusual browser caching error or technical glitch, and our web development team would need to investigate it immediately. We apologize if our customer service representatives were unable to resolve this technical anomaly for you over the phone.
Finally, we are very proud to offer high-quality, Canadian-made mattresses at highly competitive prices. We achieve these prices by optimizing our logistics, which includes setting strict delivery boundaries for heavy freight. If you would like to forward your screenshot to our technical team, please reach out to us at support@nationalmattress.ca.
