After looking around on the Lego Education website, I failed to find the price of the education software. I currently have the retail version of the software, but I want the extra features and blocks in the education version. Does anyone know how much the education EV3 software is?
The LEGO Education website does indeed not list prices, as you have to go through a distributor and get a quote there.
However, it seems that LEGO acts as its own distributor in the United States, which is slightly confusing, especially considering it's on a separate website: http://www.legoeducation.us/. There you can get prices, and you'll see a single-user license costs 99.95$ and a site license is 399.95$ (not sure how many installations that covers, though). Of course, outside of the United States you have to find a local distributor and request a quote.
