My thrift store has everything for around 15-20 dollars. If it won't fly and looks like *&^%, I won't buy it and I'll cough up the money for a more expensive suit. But I checked it out and my local thrift store does have suit coats and pants for around 10 dollars, and then about 5 dollars more, total, for shirt and tie.
As for my education, that is one area where I am willing to spend anything necessary to obtain it. I feel being educated is the most important thing in society. Far more important than money or frugality. The only other area I'd probably say that I am not frugal is saving my life, or that of a close relative. I'll spend whatever it costs.
So there are circumstances in which I'll spend money like crazy. But not very many of them.
