If you have been having issues with your shipping costs not showing properly in Google Product Search but are unable to figure out why, we may have an answer for you. Google Merchant Center says that you must specify shipping cost in either the data feed or in the Merchant Center, but not both. We have found this to not be the case. You must enter a shipping cost into the Merchant Center, which will apply the same cost across the board. If you want to specify differing costs for individual states, then you must enter shipping costs into the data feed as well. The information in the data feed serves as an override, so if you don’t have shipping costs added into Merchant Center then it has nothing to override and won’t work.
