Is it that hard to work with?

Maybe I should re-consider!
If your store is pretty new and you don’t have a lot of modules installed yet just do a clean install of GCO and it will work just fine. Don’t use Basic Authentication, and make sure the path to “responsehandler.php” inside your Google Checkout Integration is correct.
I would not make GCO the only payment processor because it is very time sensitive, and that will mess with your shipping charges. Plus, Google like Paypal is not a Bank, and don’t follow the same rules as banks, so beware.
I set the default shipping amounts to $100 or more, so that buyers will know if Google is messing up and can choose another processor to pay for their purchases. GCO has always from the day it was released had a problem with timing and will sometime not show the shipping that was shown to the buyer in your store. If a customer tries to use GCO while the server is being backed up, or its responding too slow GCO will fail. So, make sure buyer's have another option.
