Long-time lurker and first time deal poster. Came across a total of 12 discounted game-branded 1600 MS point bundles in Asda Kettering this morning. I picked up two so that left 10 on the shelves (at least when I left there was).
They're the ones with Minecraft, Trials, State of Decay and another LIVE game on the cover and they're just two regular 800 point packs in the one bundle.
They're still scanning at £15 so you need to ask an assistant to manually alter the price for you (for each one).
I'm not sure how to turn this URL into an image in the main text, so here's a link to the full-size photo I've taken with the receipt as proof.
Could be national in an attempt to sell-off such stock but I've only seen it in the Kettering store so I've labelled it as local (unless anyone finds any others elsewhere).http://www.gamerguides.co.uk/temp/cheap-xbox-points.jpg
