Garrett is the manager of Aristo Condos Inc. and is in charge of selling vacant units in the Aristo Towers . On October 4 , Heilman examined several of the units with Garrett and said he thought the prices a bit high but would think about it . Several days later , on October 7 , Garrett sent Heilman an email stating , " I will sell you anyone of the units we examined together ( numbers 14 , 236 , 238 , or 307 ) for $ 275 000. I am sending you all the details by courier . " Garrett then sent by courier to Heilman a formal offer containing all of the necessary terms , including the required down payment and acceptable mortgage financing . Later that day after he had received the email message , but before he had received the letter , Heilman emailed Garrett , I accept your offer with respect to unit 307. " Has a binding contract been formed by Garrett's email ? In what circumstances might this question become the basis of a dispute between the parties ?
