I am not trying to enable anyone but I got an email this morning about an ongoing sale for the A4box,    There is white, green and blue for 120V US/Canada.   I put the green one as an experiment in my cart and the discount code showed $149.00 with free shipping.   It comes with the smooth and ridged plates.   The additional 3 plate combo shows sold out at the moment.   40% OFF SALE ENDS TODAY
