The deal was spotted by a bargain-hungry (and chocolate-hungry, presumably) shopper and shared on the Money Saver Online Facebook page, where the post has received 7,000 comments – most of which were people tagging mates and planning weekend activities accordingly.
Asda has confirmed that the deal is available in stores only, adding that they are priced at only £3 in some stores, the Sun reports.
One 10 pack is normally priced at a quid, so a hundred would set you back a tenner. The maths whizzes among you will have already figured out that means the mega box represents a quid saving, with each cake priced at 4p, rather than 5p.
