Product Details
Effective September 28, 2014 - USPS will no longer support its RateV3 API and only allow stores to obtain USPS Shipping Rates and Service Options under their RateV4 API, which is already included in ProductCart v4.5 and higher.

If you are using ProductCart v4.1 and unable to update to the latest version of ProductCart, but need to maintain the integration with USPS, you can purchase this item. Since ProductCart v4.1 is no longer officially supported, this version of the shipping files is not included in any Support & Updates Plan and is not compatible with v4 or earlier.

Please follow the instructions in the ReadMe file included in the zip file that you download after purchase.
