I saw toysrus has $10 off any call of duty game: Link: http://www.toysrus.com/search/index.jsp?sr=1&f=Taxonomy/TRUS/22
which makes cod:mw and cod:waw $10 each.
The ones that stood out to me are modern warfare 1 and world at war if you
don't have them already. For example, cod:waw goes for $25 used at gamestop
right now. The ymmv is because some aren't available online, some are only
available in stores.
