On November 15, Gloria, Inc., a manufacturer of crystal ware, mailed to Benny Buyer a letter stating that Gloria would sell to Buyer one hundred crystals "A" goblets at $100 per goblet and that "the offer would remain open for fifteen (15) days." On November 18, Gloria, noticing the sudden rise in the price of crystal "A" goblets, decided to withdraw her offer to Buyer and so notified Buyer. Buyer chose to ignore Gloria's letter of revocation and gleefully watched as the price of crystal "A" goblets continued to skyrocket. On November 30, Buyer mailed to Gloria a letter accepting Gloria's offer to sell the goblets. The letter was received by Gloria on December 4. Buyer demands delivery of the goblets. What is the result?
