It's £79, but with the £15 attached voucher it's down to £64. It says 'available', but also says 10 weeks for delivery. However, I ordered a nunchuck from there on a different deal a while back and it said 22 weeks - it then came 4 days later!
It's still very hard to find, and as long as the voucher works it's the best price around. There are other vouchers but I doubt they work in conjunction.
