Have you checked out M-Go? Until December 31, 2013, you can try them out for free by renting two movies with the promotional code 2MOVIES. Each movie will last for 29 days but can only be watched for 24-hours after the first viewing.
If you have a Swagbucks account, you can also earn 500 Swagbucks when you go through their offers page. That's enough points to redeem a $5 Amazon.com giftcard.
Only for new M-GO accounts created between 10/03/2013 and 12/31/2013. Promotion is only valid for the first thirty (30) days after account creation. Must be a U.S. resident in the 50 states. Limit one promo code per transaction. Up to two (2) uses per account. Each use up to a $5.99 value. Excludes Disney titles. Cannot be combined with other promotional offers. The discount will automatically be applied at checkout on some devices (note: qualifying customers must manually apply the promo code “2MOVIES” on Android, GoogleTV and Samsung Smart TVs to receive the discounted price). Discount will be reflected in the emailed receipt and transaction history. Additional conditions for watching each rental will be provided during checkout. Promotion and promo codes have no cash value, except as required by law. Promotion and promo codes cannot be copied, sold, or otherwise transferred. Void where prohibited. Terms and conditions are subject to change.
