Letting buyers know up front when they can come by to check out and pick up items they’re buying saves you and the buyer from the headache of trying to negotiate your availability in several back-and-forth emails.
Simply set your availability when you list the item. After you’ve done this once, the system remembers for the next time, and it’s easy to update. When making an offer for your items, buyers may also select a pickup day and time from these pre-determined times. You can use this to help you decide which offer to accept.
When the buyer comes pick up the item, if he is happy with it, ask buyer to complete the transaction. After buyer pressed complete the transaction, the funds will be released, and it would be ok to let buyer leave with the item.
