It's not a question of being tight.
It's about not just buying this or that because it's made by a, b, or c and to my way of thinking, I use what does the job the way I want to do it and to the extent I need and sometimes I buy the because of the name and sometimes I don't.
I don't over spend and waste money and neither do I always go for cheap just for the sake of it and I always look to maximise profit.
