goofus went carpet shopping at carpetorium. he saw some carpets that he liked but could not make up his mind. mr. reganam, the carpetorium manager, wrote down the proposed purchase price for him along with a statement that the price would be good for three months. two months later, goofus went back to carpetorium to purchase the carpet and found that the price had increased. goofus showed reganam his writing and guaranteed price, but reganam said that the offer was no longer good. goofus then proceeded to purchase his carpet from carpetorium, even though he had to pay more than reganam had initially promised. he also contracted with carpetorium to do the installation. goofus almost immediately started to have problems with the carpet. goofus told reganam that he was planning on bringing suit for breach of warranty. the reganam, however, told him that the breach of warranty provisions only applied to sales of goods and that the carpet purchase was for installation, a service.
