CAGiversary!
Gladiator Begins for the PSP is priced at $19.96 at Frys.com(+ $1.99 shipping). I can confirm this is in-store as well, just picked up a copy from the Sunnyvale Frys minutes ago. I've been keeping an eye on this title for a while and this is the cheapest I've seen for the game recently.
