Thank goodness for a couple companies marking their product like they do. Back in college, if you lived on campus, you were required to get a few hundred dollars of what amounted to University Currency. USD -> University Currency (CyCash in the case of Iowa State) was 1:1, but CyCash expired at the end of the school year, could only be spent at vendors on campus, and only on food or items at the convenience stores.

Cosmic Brownies were like $1.29 as marked on the box. A box of Oreos was around $7, with all other pre-packaged item being 100-200% of a normal retail price. I bought a lot of Cosmic Brownies for exactly that reason.
