You remember how, in an effort to get you to take up their services, Google Checkout offered free processing? And how they feature that little shopping cart icon on their ads?
In a totally unrelated move, PayPal are now offering free “PayPal Express Checkout processing” thru 12/31/2007. They all feature a little shopping trolley icon. On Yahoo.
You also get $100 free credit in a Yahoo Sponsored Search account.
