Been into asda today at monks cross York to do the normal shop, was after some of this Pizza Express dressing for the wife when i spotted the huge bottles next to the normal ones, (over double in size). The normal 230ml ones were priced at £1.79, when i found a member of staff to check the price for the big one as i couldn't find the price tag...it came up at the same price as the small bottles RESULT.
Could not resist had to get a couple at that price.
500ml for the price of the 230ml bottles
Both varieties were on the shelf, cant find it online but a definite price error on their part.
