Why it matters: Netflix might still be the king of streaming services, but it's facing increased competition from the likes of Disney+. Could one of the company's strategies be to introduce a discounted payment plan for those who sign-up long-term? Possibly, as it's already testing the scheme in India.

For $6.99 per month, Disney+ can be viewed on four different devices simultaneously and in 4K, where available. If you subscribe for a whole year in one go, that monthly cost works out at just $5.83. Amazon Prime also offers a saving when subscribing for 12 months. But Netflix's cheapest plan is $8.99, only allows SD viewing on one device at a time, and has no long-term discounts.

To try and make its service more appealing, Netflix is testing discount plans in India, though they're only available for new and returning customers---not current ones. The longer someone signs-up for, the bigger the discount. Committing for three months knocks 20 percent off the subscription, six months brings a 30 percent saving, and 12 months will discount the price by 50 percent.

"We believe that our members may value the flexibility that comes from being able to pay for a few months at once," a Netflix spokesperson said. "This is a test and we will only introduce it more broadly if people find it useful."

Gadgets 360 spotted a Twitter user who posted an image of the subscription plans, which showed up on the Netflix Android app.

With Netflix seemingly raising its prices at regular intervals, a discount plan like this should tempt people to sign-up or return to the service. The question now is whether it will expand beyond India and into other markets.
