First of all, PayPal has a new look for the website. After a few weeks in Beta, they have changed some things on the regular home page. I like the changes. It is cleaner and slicker looking than before.
They have also changed a lot of the PayPal buttons. Some will automatically change for those of you who have them on your website or blog. Some will not. You can also select new designs for the PayPal buttons yourself.
PayPal has put forth a new policy regarding eBay transactions as well. This new policy went into effect on August 23, 2007. They are no longer offering promotional financing for eBay purchases. This means that if you, as an eBay seller, have high ticket items, your buyers cannot have them financed by PayPal. It could be a good thing, but it could also cause a hardship on buyers if they had planned to purchase from you but don't have the full amount you require for your item. I wonder if this will cause a drop in sales for sellers with more expensive items? It's certainly worth watching.
There are a couple of other policy changes, so you might want to login and read them all. They could apply to you.
