Not everyone knows how to ship or pack for that matter. There is part of our society that would pay someone else to do that for them, never think of doing it themselves and see no reason the buyer would have problem dealing that way. I have had dealings with similar people and they are not going to change their minds as it is the course of their everyday lives.
Just for fun, I took the OP's 20" x 20" x 15" - 60lb. box, shipped from Portland, OR to Northern Florida and ran it thru (3) shipping rate calculators: FedEx Home Delivery _retail - $107.44. FedEx Home Delivery _ using my account - $75.79. FedEx Home Delivery _ sold via eBay - $55.95 or 47% off of retail.
Ok, let's add $15.00 for (2) new boxes and $10.00 for packing material + any sales tax for your state. So retail $107.44 + $25.00 = $132.44 + tax if charged. While there are always cheaper ways to do things, not everyone would want to spend time doing so.
