Publisher Activision has dropped the price of both Guitar Hero: Warriors of Rock and DJ Hero 2 in North America.
Joystiq reports that both games have seen between $10 and $20 slashed from their various range of SKUs on the High Street.
MCV has asked Activision, but there's no word yet about whether the publisher is to officially follow suit in the UK.
However, retailers such as GAME are already offering substantial discounts on the titles.
DJ Hero 2 is currently available for £69.98 on Xbox 360 - that's a £40 saving over the RRP. There's also £50 off the Twin Turntable bundle.
The same's true of Warriors of Rock, which currently has around £30 shaved off the Guitar Pack and anything between £65 and £90 taken off the Complete Band Pack.
