We have updated our ExpanDrive store to include the option to purchase lifetime upgrades for any license or license pack. The price is 50% of the license cost, so if you wanted to add lifetime upgrades onto the 5-pack the price is $99.95. You will be able to see the total calculated before you check out.
We have also added and improved our payment options. After a brief hiatus, we again support payment via Amazon Payments.
This lets you check out using your existing Amazon account in addition to our PayPal and Credit Card options.
