Hotels and airline companies often sell rooms and seats at deep discounts on sites like www. priceline.com and www.hotwire.com. The prices for these hotel rooms and airline seats are often way below what the company needs to make to cover its costs. Airlines as well as hotel companies have their own websites wher customers can buy seats and rooms.
QUESTION: Why do you think they prefer to use priceline or hotwire for the "deeply discounted" product rather than their own website? (Note: This is not from the text and is really more of a marketing issue, but its always interesting to see the interrelatedness of the different branchs of business - so use your marketing knowledge, personally savvy or imagination on this one!)
