Useing The Zones Module as the USPS is too inconsistant to work smoothely. So we use the Zones Module. I do not get back here that often but have been using Zen Cart for 5 years. Now using version 1.3.9. Need help email me at [email protected] if you might have a way to get a product to be able to ship first class less that 3 oz weight and all shipping/packaging setting are correct. Thanks in adbance Bob
