So Marvel have announced that they're killing off Wolverine. They haven't told us how, but they have promised a four-part miniseries entitled 'Death of Wolverine' in which Logan finally meets "an adversary that he cannot win against". People have drawn their own conclusions, and as you'd expect, everyone is pretty upset:

We haven't been told whether or not we'll witness Wolverine's death on the silver screen - can the people behind the X-Men movies really consider axing Hugh Jackman? Time will tell, but in the meantime, here's some cool stuff that you can buy to, uh, pay tribute to everyone's favourite soon-to-be-ex X-Man:

Wolverine iPhone 5 Case
 £8.99 from Gadget Inspector

Wolverine Earphones
Were £12.99, Now £8.99!

Ever wondered why Thursday is called Thursday? It's because it's named after Thor, the Norse God of Thunder (see also: Friday, named after Queen Frigg of Asgard, and Tuesday, named after the Norse Law God Týr). We think that 'Thor's Day' sounds a lot more badass than 'Thursday', and so we've decided that we'll be referring to it likes Norsemen from now on.

Oh, and to celebrate the fact that it's Thor's Day, we thought we'd offer you a couple of cool deals that are tangentially realted to Marvel's third most attractive Avenger (after Tony Stark and Black Widow). Check these out:

Thor Costume (with Muscle Chest)
