This hardly compares to some of the great deals I've seen posted, but I found a plastic beaker for 75¢ at a local thrift store. When I moved recently, one of the things that broke was my immersion blender cup. The Braun replacement parts website was asking something like $15 with s/h for a new cup. Finding this one means that I can make mayo again. The sides flare out, so it holds quite a bit more volume than the old one, but because the base has the same diameter it still works for the Serious Eats 2-minute mayo recipe.
