It's interesting to read how all of you feel.
Many of you have sided with the book (with the contingency that they should compromise by giving a comp or paying slightly more than +125, but not +1255), and that's fine. I appreciate the feedback.
There are two interesting things I glean from this: 1) the fact that you're all gamblers AND you side with the book indicates to me that in all likelihood, the book is right! If even gamblers, who have a love-hate relationship with books and who somewhere in their subconscious probably want to screw all books for money lost over the years, still side with the book, then perhaps the book is indeed right.
The second interesting thing is how different this case is/should be treated vs. a similar situation in any other business. In any other business, a similar screw-up on the part of the business would definitely have to be eaten by the business. Can you imagine having a meal at a restaurant, paying your bill based on the prices in the menu and on your tab, going home, and then four days later having the restaurant call you and tell you they accidentally undercharged you, and that you have to return to pay the rightful balance of the bill? It would never happen. A business that advertises one price for a product cannot turn around and claim it was a 'mistake' -- and certainly not AFTER the customer has already bought the item.
I remember several years back, I went to the Wiz in New York to buy a big screen TV. I forget the exact numbers, but the price tag on the TV in the showroom was significantly less than the TV should have cost (and I did *NOT* notice that at the time either!). The model number on the tag corresponded to the model number of the TV, but apparently, the price was several hundred dollars less than the Wiz intended to sell it for. When I went to the cashier to pay, they caught the error...but because the price was advertised clearly as being the cheaper price, they honored that price and sold it for several hundred dollars less. And there, they would have had even more right to negate the sale/demand the higher price, because the TV had not yet been purchased -- unlike in the hypothetical case of the restaurant or the real-life case with this book, when the bet was paid days earlier.
This, I think, is a natural risk of doing business, incorporated into company's bottom lines: they have to take errors of their own making into account, and eat those costs rather than risk enraging customers who are duped -- whether inadvertently or deliberately -- into believing they're getting a product for one price and then falling victim to bait and switch. I'm sure y'all would agree with my restaurant analogy and Wiz story, that the company has to eat the cost...why is the book any different?
Just asking for curiousity's sake, please don't flame me or berate me!
(Incidentally, the Wiz is now out of business. Perhaps that tells you something
