Dude, check them out already! Some of them like Stamps.com are free, others can be as little as $2 all the way up to some crazy amounts. If you want to be on the safe side, go with Stamps.com, but make sure you clear cookies, allow all cookies and then download and try out the software, it's a 30 day free trial. Otherwise, just go with GameFly or Blockbuster as long as you've never had an account with them. Those are $10 each.
