Listed on Amazon as Knights Adventure Play set with Bonus Carry Case (5890) for £15.62 as the cheapest price.
This was £12.99 at Toys R Us so at £6.49 it's good deal if you buy in store.Available in our nearest 3 stores so hopefully elsewhere too.
P&P is a hefty £4.95 so it seems much less of a deal that way unless you buy other items - I've listed 2 other deals from Toys R Us which might help soften the price of postage?!
Sorry but I haven't worked out how to do a picture so maybe someone could help - thanks!
