Dear Zappos, I just have to tell you how happy I am with your service, selection, pricing, shipping... could it get any better?! As I am in the advertising/marketing industry, I know what it takes to really make a customer happy. I have ordered several items from you in the past and not only have they arrived on time, but early! Not only that, you've upgraded me to priority shipping when I made a mistake on an order! I am so pleased with your service and trust me... I'm a tough customer to please! Well, at east I've been let down many a time. I just wanted to let you know that you've got me for life... and I tell everyone that Zappos is best. Keep up the good work and thanks for making my feet happy. Lindsay G.
