Amazon offers its Prime members the Totally Bamboo 3-Piece Cutting Board Set for $12.99 with free shipping. That's tied with our March mention and the lowest total price we could find by $10. It features 6" x 8", 8.5" x 11", and 9.5" x 13" boards.
I had these, they are not good quality. I prefer the boards made of a single bamboo roll or one that had a couple pressed together. These are pieces glued together lengthwise. They fell apart after awhile. Stay away.
