Thank you for my new glasses, they are perfect! I will return to you for my next purchase for sure! A big thank you!
I just got the overnight shipping notification in a separate email. Thank you, thank you! You are THE BEST! Can't tell you how much I appreciate the great service. You've made a loyal customer out of me! In fact, if there's someone I can send a letter to saying just that, please let me know who I can address it to. Your follow-through has made all the difference.
