ASDA is selling boxes of 100 Jaffa Cakes...for a minimum of £3.

Stores across the country have stocked up on huge boxes of these sweet treats.

The boxes are available in store only, and are £4 in certain stores.

Still, it means each Jaffa Cake is just 4p.

A standard pack of Jaffa Cakes costs £1, meaning a huge saving.

The announcement has gone viral, with stores selling out quickly.
