You be the judge. I'm currently addicted to eBay and have been buying books from various sellers. Most books arrive in an envelope that is either padded or the book is wrapped in bubble wrap inside the envelope; one book was wrapped in cardboard. Today's book arrived in a nice, tear-proof envelope. I opened it and pulled out a bubble-wrapped book. Looking inside, I could see that the envelope was really and inside-out Priority Mail envelope. Clever, the seller took a free Priority Mail envelope, turned it inside-out and taped it up -- thats one way to cut down on overhead. They were also annoyed that they had to take PayPal and suffer the percentage cut that the company takes (I think sellers on eBay can refuse to accept PayPal. I think these sellers indicated they wanted a cashier's check, but PayPal was also listed as an option in this auction. I would note that the PayPal option seems to include the advertisement that the seller "prefers PayPal,"which really wasn't the case here). Basically, these sellers may have gotten a bit screwed on this -- or, from a different view, they didn't do due diligence in crafting the auction.
Were these sellers really, really cheap or poor? Maybe both, I don't know. Are they thieves? The Priority Envelopes are provided free of charge for using Priority Mail; they took an envelope provided to Priority Mail customers and used it for something else. Sure its de minimis, but maybe Enron's CFO felt that way. Just thrifty or lawless?
