A month ago to my surprise I sold an unopened copy of OS X Tiger 10.4.3 on eBay for $178, quite a bit above retail. Today a search of completed listings for the month showed continuing high sales at prices even above that (one topped $200). One fellow (whose bidding history I checked while my auction was going on) had purchased numerous copies, one after another, all way above retail. Any idea why people are paying prices like these?
