Marked up prices . . .

[fakename]

I also have heard that it is illegal to raise prices and then offer a percentage based discount, which is what it sounds like J and L has done. I believe that it is illegal in the sense of being false advertising, and that if there were complaints it might end up with them being fined.
Instead of figuring out the legalities though, maybe someone who has a good relationship with J and L management could tell them that what they are doing seems less than honest....
