This huge $30 / £25 Luna Controller discount has got me seriously tempted to try out Amazon’s game streaming service

Amazon Luna+ is far from the only computer game streaming service out there. But it might be one of the most flexible, thanks in no small part to the low-latency, platform agnostic Luna Controller. And it's currently available at a huge discount – you can buy it for $39.99 (was $69.99) at Amazon US.

Out of all of the Amazon Prime Day controller deals I've seen this week, this one definitely stuck out. Not only does it have a massive $30 off but, if you're willing to take the plunge and step into Amazon Luna's streaming service, it offers functionality that few wireless controllers can muster. And to make this easier, Amazon's offering a month free if you buy this bundle going for $39.99 (was $69.99) at Amazon US.

The savings ...
