Max downloads per file: Sets the number of times the user is allowed to download a digital product.

Lock downloads to IP address: If this is set to “yes”, the download URL provided to a customer will only work from the IP address used to make the purchase. Note that you can also limit the number of times a download URL will work, so we recommend you use this feature carefully.

Purchase Log Email: Enter the e-mail address where you would like sales notifications to be sent. You can enter multiple addresses, separated by commas. Note that e-mails will be sent as soon as the customer leaves your site to go to the payment gateway (e.g., PayPal, Google Checkout), so be sure to check your gateway account to verify that the order was completed.

Purchase Receipt – Reply Address: Enter the e-mail address that should be in the Reply-To field of messages sent from the store.

Purchase Receipt – Reply Name: Enter the name that you want to display in the email purchase receipt

Terms and Conditions: This is where you should put any text you want your customers to read and agree to before completing their purchase. It will pop up just before they leave your site to fill out credit card information at PayPal, etc. Note: This text will not pop up if you use Google Checkout, since that gateway bypasses the WP e-Commerce “Verify Your Order” page.

Custom Messages

Purchase Receipt: This is where you can enter a custom message that will display on the purchase receipt email the customer receives upon purchase. There are a number of tags available for you to customize the message.

Admin Report: This is where you can choose what information shows up in the email that is sent to the admin (store owner), as soon as someone buys a product.

Track and Trace Settings (only applicable if you are using a shipping service that tracks pacakges)

Tracking Email Subject: This is the subject of the email sent to the customer regarding tracking

Tracking Email Message: The Tracking Message is the message e-mailed to users when you click ‘Email buyer’ on the sales log. This option is only available for purchases with the status of ‘Job Dispatched’.

URL Settings

The location of the product list: This is the URL of your products page (i.e. your main products list)

The location of the shopping cart: This is the URL of the actual checkout page

Transation Details URL: This is the URL of the page that displays after a customer makes a purchase.

Update Page URLS/Fix Product Group Permalinks: If you upgrade or make other changes to the navigation of the site, you may need to help WP e-Commerce integrate those changes. Clicking these two links will nudge the store back into good behavior. This is INCREDIBLY important if you are changing the location of the store (i.e. moving it from a sub folder to the root).
