Estimated Shipping Costs in General Add-Ons Support Posted December 2, 2008 I have a new install on RC2.2a with the Estimated Shipping Module 1.7 installed (along with USPS Methods 2.9.6). I have it in a box on the right column. When a guest has items in their cart, the box shows up however, no shipping methods show up. If you log in, then the estimated shipping box works as it should. I have this same issue. Module works fine once logged in, but won't work for guests. Anyone have a solution?
