Rejected petition End buy one get one free (BOGOF) - go half price

We are often bombarded with buy one get one free (BOGOF) offers at our supermarkets, recently deodorant was at a well known supermarket at £3 each or buy 2 get 2 free, meaning that you had to buy 4 and spend £6 to get any savings.
With falling wages and low incomes many people don't have £6 to spend on deodorant in one go.
Also, not everyone has a car so have to carry their shopping home. Someone elderly, disabled or with young children would struggle to carry the extra items.
When these offers are applied to perishable items of food they also create waste, with the free one often thrown away.
These offers are therefore discriminating against people on low incomes or without their own transport and encourage unnecessary waste.
It would be far fairer and more environmentally friendly for the items (particularly heavy, bulky or perishable items) to be offered at half price.
I would like to see these offers restricted to half price so they are accessible to all and reduce waste.
