I visited My local Poundland today and found these great Star Wars Hot Wheels Die Cast 2 vehicle Sets on offer for £5. The cheapest I have found these is £8.99 in Toys R Us.
In My local store they had 3 variations. An Empire Strikes back one, with an AT-AT and a Snowspeeder, and two Force Awakens ones, one with a Tie Fighter and the Millenium Falcon, and the other with an X-Wing and a freighter.
There seemed to be plenty of stock in store. They don't seem to be available on the main website. If you are a Star Wars fan they were also putting out a number of Star Wars themed Christmas Decorations today too!!
