Dean, the Giant near us in Reston (Northpoint) had loose Sumos at $3.99 a pound. They worked out to more expensive than the box at H-Mart, but selling them loose would let you sample a single one to see whether you think them worth the price.
Would you be so kind as to tell Nancy we enjoyed our first pawpaw harvest this Fall? She did a nativescaping recommendation for us in 2013 which included a pair of the trees.
