Found these while looking for those ladders and platforms. Online shows $135. Found them for $26 in store. Some stores had them in side stack displays, some on shelf, some only in overheads. In SoCal they're definitely at Pico Rivera and Norwalk(in unmarked boxes in the overheads. Impossible to find!) at this price. Good deal if you need this type of work support. Need to supply your own plywood.
