Shotgun Chip Swap Mis-Fire Your Chip Lost in the mail. Ha ha

Drop [For number of Chip(s) SEE ABOVE] chip(s) in the chamber.

Again, for those of you not familiar with a Shotgun Chip Swap the way it works:

1) Those wishing to participate, Email me with your Name, address, and email address,
2) I compile a list of everyone’s information,
3) After allowing enough time for everyone who wants to participate (a few days) I email the complete list to everyone on the list,
4) Within 2~3 days everyone on the list addresses an envelope to each of the others on the list, & drops [For number of Chip(s) SEE ABOVE] Trader Chip(s)’ in each of the envelopes, mails it.
--PLEASE USE PADDED ENVELOPE--& MAIL PROMPTLY--
5) Over the next week to ten days depending on the mail, you receive new chips from everyone else on the list.

What you need are some ‘Trader Chip(s)’ chips that you are willing to trade for another chip (of potluck value), and a few stamps. You end up with new (to you) chips for your collection; and maybe a few duplicates you can keep or trade at the next chip swap. You send to everyone on the list, everyone on the lists sends to you. You can send all the same chips, all different, or mixed, but all good chips that someone might could use, keeping in mind you are just trading run-of-the-mill ’Tader Chip(s)’. The lists are usually kept to a small number so everyone is assured to have enough “traders” to mail and is not overwhelmed with mailing. If many chip swaps go on there is usually a very good mix up of the chips and everyone fills a lot of holes in their collections. Sounds like a pyramid? No, you get the same number of chips you send. Everyone pulls the trigger and all at once there will be hundreds of chips scattering all across the country. You know who does not send to you, because you have a list of who is supposed to send to you, and I believe chippers have higher ethics. This is fantastic for new chippers, or chippers that have chips from a limited area. All it costs are a few stamps, and it fun to see what you get! Anyone can host a swap and you can get on several at once if you like.
