Great stocking filler for little boys - quite good quality little toys. You can't choose the style but I've ordered 3 with fingers crossed I get different models in them.
Use voucher code 83W1 for 10% off plus free delivery (seems to be working for most people)
Go through topcashback for 5.5% or Quidco for 3%.
They're promising Xmas delivery if you order before 8am Sunday.
Also check out the deals on Duracell batteries and the gift wrap bow sets for 80-odd pence after discount while you're there.
NOTE: Photo shows a pack of 5 cars but the RRP they give is the usual price for a single one. After some to-ing and fro-ing, Charlene265 has rung M&M (thanks!) and a supervisor has confirmed IT IS THE PACK OF 5 SHOWN, so hopefully she's correct and it is 8p per car. If not, it's still not a bad deal at 40-odd pence each. Fingers crossed!
