Looking for Women's Panties with messages

Hi,
My wife made two VS panty purchases a while ago (when we were playing with orgasm denial more frequently than we are now). They had written messages of "keep dreaming" and "in your dreams" (or something like that) on the rear part. She calls them her "denial" panties and it is strictly understood that if I am getting into her pants and I see this message, I am to obey without question. She expressed an interest in having additional "panties with a message". For the life of me, I can't find a good way to search for these online, and I am not about to go into a lingerie dept. and ask for these. Can anyone point me in the right direction for this? I have seen several sexy panties via searches... such as "slide to unlock"; "all you can eat"; "today is your lucky day"; a bra/panty set that says "CTRL, ALT, and DEL"... but I can't actually find where you can purchase such panties. I think she would get a kick out of something like that for a "stocking stuffer".

You can find just about anything on CafePress but they look pretty low quality. I am hoping that I can get some higher end ones for her.

Any help is appreciated!
