To get this price you have to do three things.
1. Add the remote to your basket
2. Add the RJ11 Cross Over to take it over £30 (without increasing postage charge)
3. Pay via google checkout
This is the best price I've managed to find yet.
Don't forget to select Supersaver postage (should be £2.19)
Randomly I looked around for other cheap things to add to take it over £30, the first things I added were some foam earphone pads, somehow ebuyer thought they weighed 2KG. Thats some heavey foam to hang off your head!
