Google Checkout fee to be about the same as PayPal's
Google Checkout 2009 Fee Changes
On May 5, 2009, Google Checkout's transaction processing fees will be changing from 2.0% + $0.20 per transaction to a new tiered pricing structure, where the rates will vary depending on the amount of your monthly sales processed through Checkout.
At that time, we'll also be discontinuing the free transaction processing promotion for AdWords advertisers. Any AdWords transaction processing credits accrued during April 2009 will be applied towards transactions that occur on May 1-4, 2009.
New fee structure starting May 5, 2009
Beginning on May 5, 2009, transaction processing rates will be determined by your sales volume during the prior calendar month minus any refunds:
Monthly sales under $3,000 2.9% + $0.30 per transaction
$3,000 - $9,999.99 2.5% + $0.30
$10,000 - $99,999.99 2.2% + $0.30
$100,000 or more 1.9% + $0.30
