If you've been looking for an excuse to jump in the DJ game, now might be the time to dabble for a nominal investment.
You may not have the “skillz” to DJ like a professional but IKMultimedia's current sale might help you get there. They have reduced the price on the iPhone and iPad versions of their DJ software DJ RIG (down to $1.99) and DJ RIG for iPad (also down to $1.99). Plus they've dropped down the price of the iRig Mix from $99.99 to $79.99 with coupon code MIXIT. To get a better feel, you can read my review here.
I've tried all this software and hardware, and if I didn't own it already, I'd jump on the chance to grab it for cheap.
