Buying thread from a retail store becomes quite expensive when using thousands of meters. Before I discovered a company in Nagoya called, Ozeki (オゼキ), I made this costly mistake many times. At a retail store one hundred meters of thread costs about 230 yen, but at Ozeki, a thread distributor, three thousand meters costs only 690 yen. At that price it make the high price at the retail store seem like a crime.
