Here's my general blurb:

Following payment, I will ship this item quickly and it will be packaged well. I will work hard to keep my listings simple and create meaningful opportunities for you to receive deals on the things you want. 

I am happy to answer questions and always appreciate your important part of the buyer/seller relationship. I am aware of the important need to always be open to correcting and clarifying issues that might occasionally occur with USPS or Paypal or whatever. I will be available to you. I AM GRATEFUL for your trust.

Thanks for your interest in this item as well as in all of our offerings.

Cheers!
