JonesyMcFlyI'm not sure about how the poll is worded. It would seem that asking "how much are you willing to pay" would elicit better responses than "how much would you prefer to pay", since pretty much everyone would rather pay the least amount of money.
Still, it's good to see some follow-up on this issue. Thanks for your great work as always!
In fact, it's actually better to word it like "Would you be willing to pay $XX?" The way you suggested would still be biased toward the lowest price.
