This is often used in conjunction with an agreement to be a show home for the bathroom/kitchen/double glazing. As far as I know no one who has agreed to this has ever actually had to let any one see the kitchen or whatever. An interesting tactic here is to put the salesperson on there back foot by saying that this is a wonderful idea, can you have a look at one of these example properties?
Anyway, this comes with a substantial discount, often 60% off standard retail cost.
This sounds too good to be true, you save thousands of pounds and three people come and look at your bathroom. Well it is.
Often the sales person will call his boss (naturally a confederate and part of the tactic) and "negotiate" a still lower price, as long as you can sign the contract straight away, and please, he is absolutely desperate (see how he is building a bond? the 'phone call "just for you", probably he has talked about his family/pet/Sunday football on and off, how could you possibly let him down? Easy. Tell him you will be requesting other quotes from other companies, and feel sure that they will be using similar tactics. Sometimes this technique runs with the "special offer ends today" motif, the "last in stock" or the "offer ended yesterday, but I can fiddle the paperwork through for you" approach.

1. A board outside your property equates to a large discount?
2. Company recently moved into the area?
3. Show 3 or 4 other customers your job?
4. Our house will look fantastic in our forthcoming brochure?
5. But you must order now! otherwise your specially reserved discount will end! and  some one else will have it !
6. I must phone the office or manager to confirm if the number is still available!

One technique here is to insist that you require three written quotations from three different companies. If the salesperson asks what will happen if there is a lower quote, tell them that they won't get the sale. This should produce a realistic price. Insurance companies often operate this way, why shouldn't you?

Every company has to make a profit to pay to run their business. The gross profit margin is often 40% of their basic cost to do the job. If a company says that the job will normally cost £1,000 but because there's a 'special offer' at the moment giving 50% off, this means that the salesman will sell you the job at £500. It should be costing around £600 just to do the job, if the £1,000 retail price is to be believed the company will actually be making a £100 loss on your job. The company are either telling you porkies or they will soon be out of business.
