I agree with you totally. BUT, the difference is, if you give it to the carrier, it will go through the sorting machines and have a very good chance of getting stuck, damaged or lost. The machines move very fast and you would not beleive, and I am very serious, how much they eat. Nothing is left but dust and peices at the end of the day. It still may be flagged at one end or the other and be charged the extra .17 cents if it makes it. This does not make buyers happy. You can take the chance. Where as if you give it to the clerk at the window and pay the .17 cents it is hand stamped and hand sorted. A much better chance of safe delivery. Of course as I said in the beginning, I am a mailman and I know some of you have lost chips and I want to thank you for mailing those chips, they look great in my collection. Just kidding. ;-)
