On June 1, Art Dealer mailed an offer to Collector. The offer, which was received on June 3, offered to sell a painting to Collector. On the same day he received the offer, Collector mailed an acceptance of the offer to Art Dealer. On June 5, Collector called Art Dealer’s office and left a message on Art Dealer’s voicemail. The message indicated that Collector had mailed an acceptance, but was calling to revoke it. Art Dealer was out of town that day and was unable to check her voicemail. On June 6, Art Dealer received the acceptance and immediately mailed a letter to Collector confirming the sale. Under the Mailbox Rule, an acceptance is effective when mailed. However, an exception exists if a revocation is actually received by the offerer before the acceptance is received. On the facts above, was Collector’s acceptance effectively revoked?
