I've found that unhappy people are far more likely to give bad feedback than satisfied people giving good feedback. It's always nice when you get a rare email from a client praising your work.
I just wanted to say thanks too. Once we got rolling on this everything it has been a really great experience. You've been responsive and great to work with. Thanks for all of your help and for a great product. I'm sure it will boost sales and make our site an even better place for our users. Thanks for your help. It is a robust and very functional...in fact...amazingly functional piece of programming. I am very impressed. Thanks!!! I'm hoping you can take this to more merchants and get it rolling on a lot of other yahoo stores. I know that there is a lot of interest for it.
It didn't take much, but he made my day and it's only 10am.
And funny, one unhappy person can put a damper on your whole week. (If only it had stayed at one...)
