What are you talking about? It doesn't take any more time to buy 2 shirts than to buy 1 shirt. Maybe it adds an extra 5 seconds at the cash register, but that's not significant.
It is true buying clothes in bulk would never have entered my mind. One thing stand I have really bad experience with clothes, they break in the most awkard times, cheap clothes does that all the time in my experience. I still have my very high quality jacket I bought in 1995, it takes a beating holds up and is easily fixed.
Where are you getting your clothes? I have some pretty cheap shirts and I've never had one "break in the most awkward time". They just start developing holes, especially on the collar.
