I just messed up my order at 2:30 in the morning. I decided to buy a second square after I had already placed my first order. Kent Wang emailed me minutes after, telling me that he would send a second invoice that combined the orders. Wow. This all took place at 2:30 in the morning, I am shocked! Simply the best customer service I have ever dealt through with an online order, and I have ordered countless things online!
