I bought sausages and bacon from Asda as part of my online shop.
They were part of the 2 for £4.00 offer.
The sausages were dated on the delivery day, so I complained and was refunded.
The original price for the sausages would have been £2.25 if bought separately, the bacon would have been £2.50.
How much would you have been expected to have refunded?
