Can i sell tupperware and tastefully simple?

I am not right now a consultant for anything but I was hoping if someone knew what was considered to be a "competitor'. I know as much about direct sell as a monkey...but these two products seem to compliment each other very well. Does anyone know where I can find information on direct sale "incompatability" or does anyone have any resources as far as being a consultant for more than one company? (i.e. Tupperware, Tastefully Simple, Mary Kay, Pampered Chef, etc)
