I don't remember when Cushman's sold out to H&D, but it's been some years. Tnhey used to have a small outlet near my condo and I often went in season to buy citrus for the house. They sold by the pound and sold fruit that in those days wasn't really "pretty enough" for their bulk shipping. Still tasted great. Rarely bought citrus elsewhere in those years.
Harry and David had a store in the big mall near me - sorry to say I was never impressed with the selection nor with the quality of what I did choose occasionally, so when Cushman's was selling to them, I found other places to buy my daily citrus. Pretty much any good local market is just fine although I have yet to find the juicy goodness of the Honeybells from years back.
Never tried having anyone's fruit shipped to me although before I had to resort to a statin to control cholesteral, I toyed with ordering red grapefruit from a Texas company whose name is long gone from my memory.
