This other guy you are talking to he puts up a couple hundred different DVDs that he doesn’t actually have, puts them up on ebay, 21-day auctions with the BIN and then when some ebayer buys one he just orders it from this different website (one that actually sells it for cheaper than whatever price his auction went for hash sums fox function) and he has them ship it to the auctionwinner.
So he works at home and never actually sees his product. SHRED is a recent proposal for a sender-at-risk protocol that aims to avoid some of the defects of earlier reputation and postage-based two weeks.
