I went to home bargains earlier on, specifically for things for dd2's packed lunches...I managed to come out £45 lighter 
I did get the packed lunch bits! And freezer slushes, and candles, and bath bombs, and a wireless mouse for dd1, and drumstick squashies dry shampoo and, well, the receipt's rather lengthy & random 
Normally I'm in and out in under ten minutes in a rush to get back & to work though.
What random "essentials"
do you end up coming out with?
