Good Customer Service
I am a regular buyer of products from online stores like Mensusa. And the first thing that I look for is their customer service. If it is not up to the mark I avoid buying from that store. In this regard mensusa.com has always matched my expectation time and again. In fact at one time I had to replace a suit after a few weeks because the person for whom I bought wanted a different color and I was amazed at how courteous their customer care executives were. They replaced it immediately.
