I signed up for the year (four boxes). The first one was the Summer box. Did that mid-July; still have not received it. I contacted them and they said they would send another one, but I have not received it either. The first one they sent got to my state, but that is where the tracking stopped. Assume it was lost. But still, I should get the replacement, for which some items I originally ordered are no longer available. 
My Fall box shipped a couple of days ago. I'll see if it is worth it.
Yes, you can get some specials deals when they open it up for the yearly members; however, the day they did that, August 6, I clicked on some items an hour after it opened up for choosing, and they told me the items were not longer available. 
So, I must say that my experience so far has not been favorable, and I haven't even received a single box yet!
Doubt I will do it again next year if this is what I can expect from the company.
