Nope, just buy what I need + all the toys I can get without my household dictator putting a veto on. Do not care about news crap about consumers' confidence. It is just like late hours or Sunday trade, the idiots (big retailers) have to realize that we have a fixed amount of dosh to spend monthly the formula is very simple:
disposable income divided by the numbers of shopping hours give you the amount that can be spent per hours, increase the number of shopping hours and the amount per hours will proportionally decrease!

.But the cost of running a shop will proportionally increase , the shopping centre occupancy by shoppers per hours first will decrease and the natural selection will make lot of small shop tenants close their businesses .
On a brighter note more shopping hours will be good for people that can't afford heating or cooling their homes to go somewhere comfy for free!
