Well also as a parent and you really missed the point. There is no petrol scenario. The point was my dad always complaint about stuff which he didn't need to complain about hence why we stopped shopping together. If you not going to buy this item why complain about the price....
I am a parent too, and I love my new bulbs aswell.
I don’t feel like a mug but I do recognise I paid tonnes for enjoying this sort of new technology now, that in a few years time will be much more affordable to the masses. For the record I would put paying for fuel or clothes for the children before buying expensive luxury items.
Cheaper on prime day?
