A well-organized site leaves a good impression. Don't you love going to the dealership to purchase a car. Once you find one on the lot you think you like and you ask for more information including the price, the salesperson will proceed to ask you questions about your employment and your ability to pay and go on and on about the quality, look and feel of the car. They don't want to discuss the price until you test drive the vehicle hoping you'll fall in love with it and pay full or close to full price for it. Even after you've test driven it they will sit you in their cubicle, bring out all the paperwork hoping you're more concerned about qualifying for the loan than haggling over the price.
Some sites are just like that.
They take you through page after page of promotions and information only to get to the end of the site and there's no price. The only way you can find out what the price is, is to click on the order button. By then they hope you will just proceed with the purchase instead of clicking away. After all you have invested a lot of time at the site. A good site will give just enough information for you to make a decision.
