I left my blender jar on top of my stove, and actually used the stove.  Because the jar was sitting right near the oven exhaust port, the plastic collar on the jar got hot and melted a bit…enough to not fit on the blender base anymore. Since this is integral to the operation of the blender, I had to order a replacement.

I went to Cuisinart’s web site, and easily found the part that I needed.  What kills me is that the replacement part costs $5.00, which is somewhat reasonable, but the shipping and handling costs $5.95! I hate it when shipping and handling costs more than the part itself. Hate it. But I need the part, so what can I do?
