It means that at any time, without notice, Jamie Oil may modify, change or withdraw any or all of our fixed price programs that we offer. Once the contract is signed, however, we fully intend to honor our commitments to our customer. Just as a bank reserves the right to adjust the mortgage rates they offer, we can change the price, terms or availability of our fixed price programs. Oil prices often change more in half an hour than real estate values, interest rates, and the stock market move in one year. Iraq’s invasion of Kuwait in 1990 made the price of oil go up $ .30 per gallon in a matter of minutes. It is possible that the prices we offer on August 1st may not be available on September 10th to those who fail to sign and return the contract.
