We have been members since 2001, and have enjoyed every moment of it. The main thing that intrigued us was that they have 3 box sizes. We get the small box in late fall and winter and upgrade to a medium the rest of the year, primarily for the wonderful fruit (we can only handle so much spinach in the winter :)). They are always responsive for vacation holds and box size changes. They had offered at one time fresh mandarins and nuts to be shipped as a gift at holiday time. Unfortunately the fruit was less than par, but TFF very graciously, and quickly!, credited our account.
Additionally, they have a farm day for subscribers, which is a TON of fun. This spring they have opened up their strawberry fields for pick-your-own days (for a charge).
Their newsletter is a source of good information on the food in the box, a recipe that uses food from that week's box, and a commentary from Pablito. It keeps our family grounded where food comes from.
I have absolutely no hesitations to recommend them to our friends, which we have done a number of times.
