Twitch Prime has announced a decent giveaway for subscribers. Members can now get 12 free months of Nintendo Switch Online. And if you're a Twitch Prime subscriber who already has a Nintendo Switch Online subscription, you can still get those 12 additional months added on for free. Note that CNET may get a share of revenue from the deals featured on this page.

Nintendo Switch Online, which features Nintendo's multiplayer games, exclusives and a library of its classics, normally costs $3.99 for a month, $7.99 for three months or $19.99 if you pay for a full year in advance. Twitch is offering the deal in stages: Members can claim the first three months until Sept. 24, 2019, and then the remaining nine months through Jan. 22, 2020.

Note that all Amazon Prime members also have Twitch Prime included for free (Twitch is a subsidiary of Amazon) and you just have to link your accounts -- you can read how to do that here. Twitch Prime members have until Sept. 24, 2019, to claim their three months of Nintendo Switch Online, and until Jan. 22, 2020, to claim the additional nine months.

The price of Twitch Prime and Amazon Prime  varies from country to country. In the US it's $13 a month or $119 annually. In the UK it's £8 a month or £79 annually. In Australia it's AU$7 a month, and annual plans are also available. You get ad-free streaming and other deals in addition to the games.
