I haven't had my hair cut or coloured for two years. Doesn't actually look too bad!
Like most people on here, clothes, books, furniture mostly second hand.
We only eat out at Spoons. It's cheap and relatively tasty (and the food quality is higher than you might think - all eggs free range, fish certified etc).
No flowers - I have house plants instead which I propagate to get more (also make good presents).
No Christmas presents for anyone over 18 in the family. Saves a fortune and a lot of stress!
