Bought a mini air hockey game for the kids at Tesco at half price for £2.50. The product and game are actually quite good! The missus and myself got pretty competitive!
I can't find a pic of the exact game.
This offer seems like it's instore only as I can't find the product on the site. They had plenty of them in stock in the toy section which is currently running a half price sale on quite few items most which is old stock.
They also had a medium size inflatable paddle pad for 62p.
Girls n Boys cupboard sorter that you hang from the railing for £1.50.
Frisbees for 25p - 55p.
Worth a look during your weekly shop.
