SARA Foss spends a staggering £600 on groceries every week.

Thankfully, she says, her long-term partner and father to her 13 children, Stephen, always offers to embark on the two-hour shopping trip.

But he can't go alone. He needs three of their oldest children to help push the four packed trolleys.

Here's a list of some of their essential items bought on their weekly shop:

32 loaves of bread

75lbs of potatoes

126 pints of milk

Six bags of bananas, grapes and apples

36 rolls of toilet paper

3 boxes of washing powder

8 boxes of cereal
