wp lab is the reason why I switched over from Godaddy Quick Cart to WordPress with Woocommerce.
This plugin is amazing! I sell on ebay and Amazon. Managing inventory across all my selling channels is a hassle. I have looked into services that practically do the same as this plugin and they are very expensive ($100 per month minimum).
If you sell on ebay or Amazon, this is the plugin for you! They currently have wp-lister for Amazon beta and Matt has help me so much to get it working. I now have my inventory sync across multiple selling channels and all for a low cost!
Get the pro version to support wp lab so they can bring us more plugins in the future!
