Shopp (WordPress Ecommerce) + Shipwire
Shopplugin.net is a new e-commerce extension for WordPress. Great website, looks very feature rich…and has an integration to 4 (yes all 4) of Shipwire’s API’s. Live Shipwire shipping rates in your Shopp checkout pages. Orders are automatically sent from your Shopp store to your Shipwire account. Inventory is synchronized between the entire Shipwire warehouse network and your store. Tracking numbers are also synchronized for completed orders. Sweet!
