Its plastic bricks FFS!
I can sort of see why the branded stuff (Star Wars etc) is more as they have to pay for the rights to use the brand, but even the standard stuff is exorbitant for what you get!
I have managed to avoid it thus far but after a play date a few weeks ago, DS i now hooked. I have a set budget at Xmas anyway, but this year it is set in stone thanks to redunancy followed by a NMW job, and what I can get, even with super savvy shopping, is pitiful :(
