10$ Newegg Rebate?

[Slash003]

Hello I got a 10$ newegg rebate and I'm wondering what to spend it on. If I dont get any suggestions I'll get this for my skullcandy so I can use inline mic:  http://www.newegg.com/Product/Product.aspx?Item=9SIA07Y02A5359&cm_re=dual_mic_and_audio-_-9SIA07Y02A5359-_-ProductI'm also looking for a fan controller. Any suggestions are appreciated.

does it expire? if not you can always just get a few more bucks off whatever it is you want to buy down the line.

I'm not sure or not if it expires, its a coolermaster case rebate.
