Yes they do. It applies to members who have less than 100 feedback or who created their accounts less than 6 months ago. It is applied to things that sell for more than $100. The money is held until the buyer leaves you a positive feedback and usually within a couple days you'll get the money released. Otherwise if they don't leave positive you'll have to wait a couple weeks before it's released. Not quite sure on exactly how many days but it's on the eBay site just go read it for yourself.
