Suppose the Hills had purchased the computer as a birthday gift for their daughter, but didn't open the box or give it to her until her birthday two months after the purchase?  Or suppose the Hills took a long deserved six week vacation to Europe after ordering but before opening the box?  Or suppose the Hills were hospitalized following an automobile accident and didn't get around to opening the box for six weeks after it arrived?  Would they be able to return the computer for a refund if they didn't like the terms? 

     Suppose that after shipping the computer to the Hills but before the expiration of 30 days Gateway called the Hills and raised the price $500.   If the Hills decided to keep the computer, would they have to pay the increased price?
