I couldn't have said it better myself (although I've said it before). This from Joseph Jaffe in response to the guy who paid $351,100 on EBay for lunch with Warren Buffet,
The proceeds of the auction on eBay go to charity...but underneath it all, is a a stern lesson to all the marketers and advertising practitioners out there who fall victim to continous discounts, sales and undercutting the competition: consumers will pay a premium for value - especially with there is an experience which comes along for the ride.
Don't base your price on what it costs to produce the meal or to clean the room, i.e., mark-up's. Instead, ask yourself what's the experience worth?
