Google Checkout is being eliminated by Google on November 20th, 2013. As of November 15th most merchants will no longer support Google Checkout/Wallet for subscriptions. They should ask you to update your billing information into a new billing system to continue with your subscription. Of course Paypal is still going strong and seems to be more reliable over the years.
You do not have to do anything with DWHS or WebHost.pro (same company), this is just a warning for other services with other companies you may use that have excepted Google Wallet. From October 25th to November 15th you may need to update your billing information or your Google Wallet subscription will expire.
