Well it's rather nice when the Sainsbury's toy sale fits in with the day I start my Christmas shopping (after the last family birthday of the year).
I was expecting inspiration for something for my baby, but most of the infant toys were unbranded tat. But there are very good deals on nerf guns - I got large ones for assorted nephews, nieces and godchildren at half Amazon price. And little Nerf jolts for my teenagers and DH's stockings for £3 each, because Christmas isn't Christmas without starting the day with bullets flying. 
I also got Hatchimal Mystery mini eggs for about £4 each. They were selling fast so either bargainous or people betting they'll be in short supply.
