Try cambridgesoundworks.com and the student advantage coupon code (SADVANTAGE15 or SADVANTAGE20, one of them should work)... Sometimes you can get free shipping from them too as a seasonal promotion. That should cut it down to around $55-60 shipped and brand new.
Why not just buy from Headroom. $69 + free shipping and the peace of mind of buying from a trusted seller. Plus if you don't like them for some reason, you know you'll be able to return it with no problems.
Todd the Vinyl Junkie is usually running a 10% off discount on "select headphones" which included the SR60s when I bought them. After the discount, the total came to $67 shipped. Todd was also a great vendor that I would highly recommend.
