You will have 30 days from the end of the rental period to either upgrade your rental to a purchase or send the rental back to us.  You can upgrade your rental from your account (Sign In –> My Rentals –> Upgrade).  You’ll be charged exactly 0.6667 times your original rental price to upgrade it to a purchase. For example, if your rental price is $60, then the additional purchase upgrade charge will be: ($60 x 0.6667) = $40.
