I guess OP, different people have different priorities, but also different expenditure and income in very similar house holds.
Often you see on threads like this "how can anyone afford XYZ?" - this is the first I've seen on gaming, but I've seen people ask how can anyone afford a £20k wedding, to buy a house, to drive a powerful new car, to smoke, to eat out all the time, to buy a designer handbag, to have AI holidays in school holidays.
When you drill down to it, what the OP is asking on each thread is really "how can they afford XYZ assuming their income and all other spending choices are exactly the same as mine "
and the answer is always "they can't, either their income is higher than you thought and/or they don't make the same spending choices as you elsewhere."
for the record, we only own a Wii and don't really use it much and haven't bought a game for over a year, but our DCs are small, on the other hand, I have an £800 handbag - which works out as £15 a week over a year, or less than 2 packets of fags a week, or less than 5 boots meal deals a week for those who don't make their lunches for work....
