I finally got around to selling on . This is my first trial offering. This chip just happened to be on a table in my office. I wondered about what to start the bidding at and what to charge for shipping. I settled on $00.01 with shipping at $2.50 figuring most people know enough to factor shipping into their total cost and wanting to cover my costs if I only got a minimum bid. I did not offer insurance because it would not be worth my time standing in line at the post office to get insurance for a single package. The bidding is higher than I expected.
