Yahoo just announced on their blog that product search results on Yahoo will now show little blue shopping cart icons next to those listings that accept PayPal. This partnership with PayPal is a direct hit against Google's Checkout system. I love it. First of all, I use Yahoo as my default search engine, and second of all, I am always looking to see if the store I'm about to purchase from accepts PayPal or not. So, voila, this was made just for me! 🙂 Thanks, Yahoo!
