best way to ship back a monitor for repair

Hello... deny insurance and Delivery Confirmation will reduce your costs. Also just take some brown paper sacks and cut/tape over your monitor Box... Adding a BOX around it will increase it's size and increase your shipping costs. UPS/FEDX/USPS will have similar shipping prices and various shipping time methods... ASK for nothing fast or special and use ground to reduce your shipping costs. With that size of a Box you will get automatic online tracking, with no additional fees.
