Over the years I have had several thank you notes in purchases that I've made but the best one was a purchase that I made last year.
I had purchased a 5 card lot of T59's on ebay and a day or two later I received a message from the seller letting me know that she had shipped the cards and that when she was getting my order ready she had found 2 more T59's and she put them in my order for free.
When my purchase arrived along with 2 extra T59's there was a hand written receipt and a thank you card. The grand total of my purchase with tax was $2.81 and the shipping was free.
