I stumbled on this site tonight. Cheap shipping too.
Firesteels for $2.97 (they list them as magnesium, but I think they are ferrocerium) http://www.widgetsupply.com/page/WS/PROD/specials/SDD2-FS373
Keychain knives with a 420HC stainless blade and a titanium handle for $6: http://www.widgetsupply.com/page/WS/PROD/pocket-knives/SGS3-K12201
