Google Checkout and the horrific UI

Google Checkout - the PayPal killer is - out and boy what a horrific user interface!

I haven't really used it yet, but I tried to get some help... And in this process I got totally lost. How it happened? I wanted to get some help, so I click on "Help" link in the right corner - this changes the whole interface! Fine, I got the needed help and I want to get back. I click on "My account" in the left menu. This takes me back to Google Account Manager, where "Checkout" isn't listed!? I click 3 times back, but whoops I am back on the sign up page...?

Google, this can be done much better! Wow, this isn't bad UI design, it's horrific! The interface lacks indication, the help system and "My account" aren't that well integrated with each other.

I found out that one has to click on "Purchase History" to come back...

A little graphical representation of how to get lost:

Getting lost with only one click

Click "My Account", whoops, the only way to come back to "Purchase History" is to use the back button...
