Smythe wrote to Lasco Dealers inquiring about the price of a certain freezer. Lasco wrote her a letter, signed by its credit manager, stating that Smythe could purchase the freezer in question during the next 30 days for $400. Smythe wrote back the next day ordering a freezer at that price. Lasco received Smythe’s letter the following day, but Lasco wrote a response letter stating that it had changed the price to $450. Smythe claims that Lasco could not change its price. Is she correct?
