Didn't see this posted yet, so hopefully it wasn't
Thinkgeek is having a clearance sale, and the BF4 Razer Peripherals are on sale.
If you're an e-mail sub to Thinkgeek, you should have also gotten an e-mail with a 25% off sale items this morning, bringing them down even further I believe it's a unique code.
Keyboard: $50 - $37.49 with e-mail coupon - Keyboard Out of Stock as of 12:40p Apr 8th
Headset: $50 - $37.49 with e-mail coupon - Headset Out of Stock as of Apr 9th Morning
Mouse: $40 - $30 with e-mail coupon
Mousepad: $20 - $15 with e-mail coupon.
Edit: Looks like there's a 20% off coupon that will work with this also if you don't have the 25% - "FIFTHOFF" - Thanks Roguestriker
If you order over $50, apply code "RETAILMN10" for $10 off BEFORE applying the 20 / 25% coupon. (TY Weeman!)
