We have a Magento free extension from RocketWeb Extensions for Google Base ([url removed, login to view]). The extension works great, except when grabbing the special price from Magento
About 20% of our inventory is managed by us the other 80% is managed by a third party and their script. The special price for the 20% is grabbed just fine. But the extension does not grabbe the special price for the 80%, even tho it exist in the magento back-end and product page.
RocketWeb wanted $95 to do this for us - we are looking for someone that can beat that.
