My son has this and plays with it every day. :)
John Lewis are saying it's half price (was £14.99) but I know it was only around £11 when my son got his - even so, I think this is a really good price.
Free collect from store (John Lewis or selected Waitrose), or delivery charges from £3.
Other Iron Man items are also reduced, will put links in comments.
Credit goes to Playpennies for posting the toy sale at John Lewis where I found this (I hope they don't mind!).
