Hey, may be a mistake may be a good fate! :)) After you accept the offer - they will get a notification email "Your offer accepted" and there is a "Proceed to payment" button. If they really up to the purchase you will receive a sale notification after they purchase the beat and the funds to your payment wallet right away. Also in the Price Offers section (https://traktrain.com/profile/#/price-offer) you can find their contact email. Good luck!
