If you’ve never used Amazon Prime to stream video, doing so today will get you a $10 Amazon credit to spend by Prime Day. All you have to do is sign up for a 30 day free Prime trial if you aren’t a member, open up the Amazon Video app on your smart TV, streaming box, or game console, and watch any free movie or TV show included with your Prime membership.

Assuming you’ve never done this before on the same Amazon account, you’ll receive a $10 credit in your account within 3-4 days, which will expire at midnight on Prime Day.
