It will be an ultimate black Monday fdi special.... Buy an anti-gravity machine and a time machine together and shipping is free. If you ship them turned on, you could get a free shipping and they'll arrive before you ship them.
To keep board flat, get an archival box the size of the board and store your board in that. If your board still warps, put the board in a plastic bag and then put the wrapped board in the archival box. This will take up no more space than just putting the board under your bed. And the board will definitely stay flat. We can supply the archival box and include a free large plastic bag. The board, too, if you want AlphaRag ArtCare. We would ship it to you in the box.
