As a side note, there are all the "as seen on TV" things.

Typically they are US $3-8 worth (price) i.e. US$ 1.5-4 worth (value/cost), advertised on TV as the "ultimate whatever" with a "shop price" of 50 $ but - only for tonight - 29.99 and sometimes (big offer) we will send you two of them for only 39.99.

Then a few months later you can find them on e-bay (or similar) for anything between 3 and 8 $.

For some strange reasons I am fascinated by some of this crap and tend to buy it (when I can find it at the lowered 3-8 $ price), and - surprisingly - it is actually IMHO good for the 3 or 8 $ you pay.
