Just picked this up in the Poole store - seems like a bargain price compared to other (current) deals I've seen online etc.
Can't find it mentioned on the Sainsbury's website, and not sure whether it's nationwide or not. However, the Poole store isn't the biggest in terms of electronics etc so I'd have thought if they have it then elsewhere will have.
I'm also not sure whether it's the 'new' remote or not as I only glanced at the box when they brought it out (image is just one I found online), but can check later today.
Hope this helps someone!
