This may not be applicable to every location so it's definitely a case of YMMV, but my local TRU is running a special on all 360 games: Buy 1, Get 2nd 1/2 off (price of 2nd game must be equal to or less than first).
This appears to be running (IIRC) Aug. 15 thru the 21st.
Additionally, that same location closest to me had a giant stack of new ELITE BEAT AGENTS for the DS priced at $9.99 with an additional 20% off.
