For those interested in quirky details of Google Checkout, read on :) Others, don't blame me for the long post. You've been warned :)
I have my domain lakkaraju.net registered via Google Apps Standard Edition provision via Enom.com. The account is setup for automatic renewal on my credit card via Google Checkout. Easy and convenient for use. I'm not getting into the security aspect at the moment.
Google sends out a mail about 2 months in advance of the domain expiry date that the domain is about to expire. Offers an option to renew the domain on that date or have it happen automatically via Google Checkout about 15 days prior to expiry.
I chose the "automatic" renewal option. On the d-day of "automatic" renewal, I didn't see any notice. After the d-day, when I went to Google Checkout, the site doesn't show the order details. However, when I login to my apps account, it shows that renewal did take place.
So, either something's wrong with Google Checkout billing details or I'm missing something. Don't know if this is a known issue.
