Frameco sells license plate frames engraved with custom messages. It sent a "Dear friend" flyer to several hundred potential customers, including Adtech. Frameco's flyer said that it was offering frames at $1 per item. It further specified that orders had to be for at least 1,000 frames and that the inscriptions could have no more than 25 letters each. Adtech faxed Frameco, "Send me 2,000 frames, at $1 each, with the following inscription . . . ." The inscription contained 22 letters. The next day, Frameco called Adtech to say that due to an unforeseen increase in the cost of production the purchase price had risen to $1.25 per frame. On these facts, can Adtech sues Frameco for breach of contract? Why or why not?
