$75 e-Gift Card at Sonic Electronix

The following review is for SonicElectronix-75-Gift-Card, which is a part of the bundle you are viewing.

Got this bundled with the DC 90.4 which is a awesome deal. Everywhere else the amp was $500 sonic had it for less and it came with a $75 dollar credit so I get even more off my next purchase. Basically like getting the amp for $350 with my code taking off an additional 5%.
