Pinnacle Cart does support the auto-return function within Paypal.com.
1) To activate this, you will need to login to your PayPal Account and go to your profile.
2) From there select Website Payment Preferences under the Selling Preferences heading.
3) Turn the Auto-Return to on.
4) You will enter in your domain name for the return URL (domainname.com)
Note: If you have turned on Auto Return and have chosen to turn on "PayPal Account Optional for New Users", a new user will not be automatically directed back to your website, but will be given the option to return. You can find the Paypal Account Optional setting on the same page as the auto-return settings.
