Thanks for the file Dcully, Thx Jim for the info. I had my tare set to 0 but had the 10% for heavy.. Also was set to online as I thought being an online store it would need to be set to online. I will give this a test run and see what happens.
One of the main problems we will have is with the new rates that USPS has placed with the 13 oz or under will ship flat but anything over 13 oz auto goes to first class priority. My shop is in the same building as the post office so we only use them to ship with. To easy to walk two doors down and ship.. The postmaster and I are good friends and he is telling me more changes are going to happen soon.
