Google Checkout

I know it's JUST come online, but has anyone looked at Google Checkout for processing?

They have an API. Are there any plans at Dydacomp to integrate it?

Google charges $0.20 + 2% per transaction, but they waive those fees at the start of each month for transactions accumulating up to 10x whatever you spent on Adwords ads the previous month.

We have an existing shopping cart and often need to substitute or adjust quantities, so we don't want a system that charges up front, but that rate & Adwords discount look tempting.
