I don't know about you but when I go shopping, I look around for the cheapest option. I hate paying pull price and will use discount vouchers or take advantage of sales if it means what I am looking for can be sourced cheaper.
The majority of my visitors are looking for the same thing.
They are looking to find a satellite navigation system for the least amount of cash. They land on my site, find a system and look for the cheapest price. They then go to the cheapest retailer and place an order.
Nice theory but it is not like this is practise. More
