Okay bankrupt may be going a bit far but..
DH is normally tight with money - he believes that changing a toothbrush more than once every six months is extravagant - but for some reason every year on Amazon black Friday he seems to lose the plot. He hates Christmas because it's a "bloody waste of hard earned money" yes he is northern but he has just spent a fortune on tat for the house, including a new computer chair that was a bargain at £90 but is just a cheep blue swivel chair that staples sell for £40. We already have four computer chairs ffs!
