The cost of shipping is not just a per pound cost only, if you shipped 20 little light individually and shipped another box with 20 LL's in it you would find a huge difference in the costs with similar weights (in total) UPS has curve in costs where a mid size box with ideal weight can much cheaper that 2 boxes with the same cargo, HL's box's are sized to hold like 6-9 pieces per box. Box size gets to big - shipping fee goes way up, weight gets to high - shipping fee goes way up. Carriers like mid size ideal weight boxes so they can be handled easily and quickly (cost effective)
