As per title, 800g jars of Hellmann's Mayonnaise are £1.42 and BOGOF in store at Tesco.
The 800g jars of the Lighter version are £1.41 and BOGOF.
This was advertised on signs and shelf edge labels in store.
This deal is effectively half price and BOGOF, which suggests it's a mistake and maybe this explains why it isn't showing online. It certainly went through the tills just fine half an hour ago.
I see that this deal was mentioned in another thread where there's a similar half price and BOGOF deal on tuna and sweetcorn.http://www.hotukdeals.com/item/648258/john-west-tuna-4-packs-bogof-at-2-6
