As a kid I used to love seeing those demonstrators at County Shows and local markets.
They would demonstrate a product (food choppers were popular then) to its best and suggest a very high price. Then before the people started to drift off the hawker would stop them and say - "but you look a friendly crowd and I want to do something really special for you. So, for one day only, I won't charge you £50, not £40, not £30 etc.... today, just £10."
Over the years I've seen a similar approach adopted in direct mail and on line copy. This normally involves including multiple bonuses with the product and then giving the total value. Once the "value" is established they come back with the market traders trick "but today, not £1,200, not even £1,000 ...."
Tie this in with a limited offer and you could boost your response. Of course, this wouldn't work with every product but where the product is price sensitive, it could be worth a try.
