Dear Zappos,
I don't know how you guys do it. I placed my order late in the day. I received my daughters sunglasses the very next day by UPS. I remarked to the UPS man how fast the package arrived. The UPS man simply replied "These guys are good." I just wanted to let you know that not only did you impress me; you also impressed my UPS man. This was not my first or last order from Zappos. Congratulations to you and your amazing team.
