Take a look at kohls online. They seem to be taken over by the Food Network. So many of their items are Food Network, I"m starting to think they own them.
I think it would be easier getting ingredients out of the cup, than a standard one with corners. Trying to scoop shortening out of the bucket is a pain, and I never really get it all out of the cup. The sticks are nice, but way more expensive (especially when I'm making 5 pies this Thanksgiving).
Even dry ingredients would come out easier, like flour.
