You have ordered 100 shampoo bottles from an online supplier based in Port Macquarie on the north coast of New South Wales for your store. The contract of sale doesn't specify the place of delivery. You assumed that the shampoo would be delivered to the hair dressing studio in Parramatta, but the supplier says that you must arrange to collect the shampoo from Port Macquarie or pay an additional $2 per shampoo bottle for 'postage and handling.' Do you have to pay this? Give reasons.
