Have you tried out the Amazon Local Deals yet? Today is a great way to get started! There are a limited number of these $3.00 off vouchers available. You can use them on your video rental purchase of $3.99 or more.
Amazon Local is easy. Just select your city (Houston for me) and enter your email. You will need to add your credit card number but it will NOT be charged. I know I just grabbed one for me!
