This is definitely a great opportunity if you live in canada..If you're in the US, it's ok, you get five bucks off. But in canada its a problem to get these especially new (bay bloor radio wants about $130CND for them...plus tax)
that is a great price. I think he has SR80s for around $80 too.
Only drawback is that Grado does not recognize them as an authorized retailer so the 1 year warranty is void. I'm sure you can still return them for repair, should they need it. But you'll have to pay for the service from day-1.
