Also, is there a support phone number anywhere?
Piggybacking their own bulk email lists on top is a no-no, even if it is part of the Google Checkout option, imho.
What if you created the Google Checkout account for them? could you act like a gate keeper for his e-wallet? is that possible/legal?
You know, taking the credit card data from the user, storing it in your secure app, creating an email address within your app, submiting info provided by your user to Google Checkout and then when a payment needs to be done:
User needs money to pay something you are selling -> Your app then goes onto the Google Checkout account of the customer and tries to get some money for you.
You basically are making your own API on top of the current Google Checkout. Maybe using scraping and stuff (just like how InDinero scrapes and get your bank data).
I'm asking because I cannot verify if this indeed can be done. I cannot create a Google Checkout account since I'm not from the USA.
