These have been around for a trillion years, and are decent tomatoes. Every super market in the mid-west I have been to has them by the droves, nothing special.
they are like green housed heirlooms. a small margin better than the out of season 4x4 tomatoes and if tomatoes are in season like they are now.... i wouldnt pay the outrageous prices for those ones.
