On October 12, James Camp agreed to provide services to Shawn Sheth by October 15. In payment, Sheth gave Camp a check for $1,300 that was postdated October 15. On October 13, Camp sold the check to Buckeye Check Cashing for $1,261.31. On October 14, fearing that Camp would violate the contract, Sheth stopped payment on the check. Also, on October 14, Buckeye deposited the check with its bank, believing that the check would reach Sheth's bank on October 15. Buckeye was unaware of the stop payment order. Sheth's bank refused to pay the check. Buckeye filed suit against Sheth. Was Buckeye a holder in due course? Must Sheth pay Buckeye?
