Jane bought some tuna the other day.
She thought we were running low on tuna.
We had six cans in the cupboard.
But she went online and ordered from Asda (not just tuna you understand).
And they had a special offer. A double special offer. John West were doing a six pack for the price of four cans — Asda went one better and were doing two-for-one.
We now have 18 cans of tuna!
Guess what I’m having on my sandwiches for lunch today?
