Apparently when you order groceries for delivery and allow for substitutions, this may result in you being brought LESS PRODUCT BUT FOR THE SAME PRICE as you anticipated paying. This applies even when the correct amount of goods could have been supplied by the store (exact same brand, just different size packs), but they failed to do so.
I queried this with Tesco Customer Services and they confirmed this can happen, and they are not prepared to make any further refund (we are talking less than £2 against an overall grocery order in excess of £100.) Apparently, I should have just rejected the substituted items if I was not happy with them.
They even followed up with a Tesco Price Promise email telling me how much I'd saved by shopping with them instead of Asda/Sainsbury's etc - what a joke!!!!!
