I have a item sold and the simple delivery has charged upon purchase for the buyer to pay. He lives local and messaged to ask to collect the item instead of waiting for delivery. How do I go about this if simple delivery has already been initiated by the purchase and a DHL collection of parcel arranged for 2 days away. Will the buyer be able to pick up and not use the delivery method? Will this be refunded to him or just lose out on the delivery fees? Is the simple delivery a unavoidable option to change once it's been assigned to the purchase of the item? Thank you
