In Germany there is § 138 BGB [0], forbidding a "conspicious misproportion" of price and service. I assume other countries must have similar laws.

This law is more so for cases where a standard price exists

I guess most countrys have something like this. Just is there any case, where a judgment was ruled on this anywhere?
