EB Games has this headset listed for 18% off in their online store as well as on eBay. It works with the PURCHASE5 code (and probably others if you spend enough in one transaction) so you're better off buying it on eBay (and postage was $1 cheaper on eBay for me).

Not 100% sure when this expires, it's part of a "Best Sellers" sale on EB Games' site. eBay shows the listing ends 31st of March but the discount could be removed sooner. If they're sold out or the deal ends, try EB Games' website, your local EB Games store, or check out Mwave. They have a $20 discount on both the MH752 and MH751, and they include a free hat.

Looks like a decent headset, haven't used them myself, bought a pair a couple of days ago with this discount and waiting for them to arrive.
Watch this review for a good idea of what to expect from this headset (and a bit of entertainment), but take it with a grain of salt.
Edit: Tagged this deal as "headphones", all you have to do is detach the mic. They have a nice plain design, are very comfortable and great for listening to music, since they're based on Takstar Pro 82 headphones.
Edit 2: Back in stock, relisted with 2 headsets available. Will keep updating this deal as they sell out/restock.
Need a new headset, can anyone comment on the quality in the build? My razer man'o war 7.1s were amazing sound, but their quality in build was TERRIBLE. Flimsy plastic that broke quick.
