We are continually looking to improve on our products, and occasionally we may introduce a new version of the product that improves on the previous versions in different ways. As a service to our customers, customers may upgrade to the latest version of the product at discounted pricing.
Please read our upgrade policies:
Customers do not need to send in their older version products if you purchase the product originally from us, we will locate your original purchase record under your name. If the purchase was made under a different name, please notify us so we can locate the correct record.
If you purchased the products used and am looking to upgrade, please note that if the original purchaser had already upgraded once, you will NOT be eligible to upgrade. Please provide us with the name, city and state of the person you purchased the product from and we will try our best to locate the original purchase record and upgrade history. If we cannot locate the record, we apologize that you may not be eligible for the upgrade.
Limit 1 upgrade per product purchased. Please note that if you upgrade and sell your earlier version product to someone else, he will not be eligible to upgrade again.
