Google checkout - recurring billing 
One feature I would love to see is to have the option to use Google Checkout's recurring billing feature... it is currently in beta (please see this article: http://code.google.com/apis/checkout/developer/Google_Checkout_Beta_Subscriptions.html )
Authorize.net and Paypal Pro both carry sizable monthly fees associated with recurring billing, so if Google Checkout can be used to run subscriptions for recurring payments, this would be very helpful for our nonprofit!
Google Checkout has been retired in the end of 2013. See https://checkout.google.com/seller/fees.html
Sorry - no progress here yet and it looks like none is expected in 2011
Yes, i believe it would (purchasers have to have or create a google account anyway to purchase via GC).

Thanks for posting. Do you know if recurring subscriptions require purchasers to have Google Checkout accounts?
