Not all VPN tunnels are encrypted. If it's an IPSEC tunnel, it can include AH (packets are authentic, but not encrypted), ESP (packets are encrypted but not authentic), or both. A lot of VPNs these days just use SSL - same as your browser, which will always encrypt, and may or may not authenticate.

Maybe... Watch for the padlock icon and a certificate warning. If you get a warning, then the VPN provider is intercepting the SSL traffic and repackaging it, which means they can see the content. If you have a padlock icon, and no certificate warning, and the URL in your browser address bar is Barnes & Noble, then it's likely that you have an end-to-end tunnel from your browser to B&N.
