At 27.1p per 100ml this actually works out to be the cheapest Heinz ketchup in the supermarkets at the moment.
Offer on until 20th January.
Been meaning to try this for a while as I go through gallons of the stuff, but it's always cost too much more over the regular stuff.
Until a 900ml for £2 offer on normal ketchup comes back, this is the cheapest Heinz ketchup going, unless you can find some in B&M maybe?
Might turn out the healthier stuff tastes rubbish, always wanted to try it though as I think it's nearly half the calories. If it's decent, might buy a few bottles before the price jumps back up.
