I am having a terrible time with the USPS shipping plugin. It has been working fairly well for several months (although with a handful of bugs). Then last Thursday it stopped working, disabling our site checkout process. The issue cost us a day of business. In the mean time we have installed Premium Shipping as a patch, but we really need a shipping plugin that takes API from USPS and UPS because of the wide range of products, products sizes, weights, dimensions and geography.
At this point I am open to any and all solutions, hiring someone who will solve the issue, has experience in this area, whatever it takes. Maybe there is someone out there who has similar problems with ExtensionWorks USPS plugin. The UPS plugin works, but takes a while to load. So we also need to optimize that plugin.
Thank you... I'm desperate to resolve these issues so that we can return to business as usual.
