Garden World orders 120 hand cultivators from Green Thumb, Inc. When the cultivators arrive, they seem fine, so Garden World accepts them. As the stock person is putting the cultivators on display, she notices that the tines are loose on all the cultivators. Garden World returns the cultivators to Green Thumb, but they are lost when the delivery truck slips on an oily spot in the road and drives into a nearby lake. Discuss who bears the risk of loss for the shipment.
