Free ship is continental U.S. only.

Until the summer of 2014 Earthbox was on sale near constantly but they were bought out and the sales dried up. Their current bundle deals (at least #2 and #3) are actually a very good price, including 2 boxes and the automatic watering system. There is an organic option also.

I have multiple boxes the oldest are 4 years old and indistinguishable from the 1 year old boxes. The automatic watering is fantastic.
