Thanks
Thanks for the suggestions guys. I will try the bmx section as well (though they are usually the same).
I also realised that the mag contains a "Dealers" section which lists all the places that order the 10 pack. This didn't really help me because the closest store is still a pain to get to but it might help others.
You can go to the [R] website and view the last issue to get the latest - 1 dealers list.
