Thanks. I also thought about splitting the shipping if I could find anyone else that was interested but from what I can tell the $25 isn't a flat fee and tends to go up considerably with each sheet added.I feel your pain. I went down the same rabbit hole a while back and ended up giving up. If you find a source, PLEASE let me know. Maybe others in SLC will come forward and we can split shipping?
What did you end up doing for your sideboards?
