Amazon is currently giving $1 Instant Video Credit if you opt for their slower No-Rush shipping option when purchasing items eligible for Prime shipping. As far as I can tell, all Prime eligible items qualify for this promotion, even items that cost less than $1. This means, you can get $1 video credit for spending less than $1. The cheapest Prime eligible item I could find is this $0.12 compression sleeve. Sure enough, when you add it to your cart, the $1 video credit option appears. Since there doesn’t seem to be a limit to how many $1 credits you can earn, you can technically purchase this $0.12 item numerous times and essentially buy Amazon Instant Video credit for 88% off.
