BIN is a different story. I think eBay changed something so that making an offer on auctions became a default or something withing the past few months and it drives me crazy since 'make an offer' in the past was always only associated with BIN. It is pretty pointless, since you can't make an offer once there has been a bid.

I've never encountered that. When I'm ebay buying I routinely make offers that are much less than the list price (if it's fairly high.) Sometimes they accept. Just be polite and nice in your message with the offer, explain why it's a fair offer from your perspective. Al, why not offer $5 or $10, explain you want to try data recovery for bitsavers, but the disks may well be unreadable. It now has 5 watchers. Maybe they are all members of this list, maybe not. I assume you are aware of snipe-bidding services? Some of those watchers may be too, but you won't know till after the end. I've used bidnapper in the past very successfully. >If nobody else bids, then it will be cheap, other than the shipping (the >seller does not seem to know about media mail: "Computer-readable media >containing prerecorded information") He will know if you tell him.

Back in the day, I was working with a group on a four-month project, where the final version on 8" floppies of the (source) software was put on display for a little celebration. Management sprang for bottles of bubbly, some munchies and some T-shirts--and the department had a small party. What no one noticed until the next day was that the stack of floppies had been soaked through with champagne, and put away for the weekend. Monday arrived--and the disks were a sticky mess. Fortunately, the treatment of washing and re-jacketing did the trick. But there were some very nervous people in the meantime. Needless to say, we made several backup sets and sent two of them off to the vault. --Chuck

Rubbing each edge of the jacket firmly perpendicularly against the edge of a tabletop, so that the jacket bowed out SLIGHTLY, often helped substantially.
