If anyone's buying Lego for Christmas they've got 7.7% cashback on Quidco but you get a £50 bonus if you spend over £100. So you'd get £57.70 back from £100!
I've been waiting to buy my little boys on Black Friday thinking I'd save 20% or something but didn't expect to get so much cashback.
If you don't have Quidco I can send you a link and We'd both get a £5 bonus too xx
