I have been purchasing Bountiful Baskets for a little over two years now.
I participate every other week, that's plenty for me. I have found that the summer baskets are very full and the winter time is a bit less but still good.
As for quality, it just depends on the item and season. Berries tend to go bad fast, just like they do in the grocery store. The bad items are minimal.
I volunteer most every time and leave with a few extra items and a good feeling.
Over all I feel its a great value and I enjoy the surprise of trying new items that lead to new recipes. Recently received two delicious Casaba melons, a fruit I have never tried and most likely would have never purchased at a grocery store.
