Yes there are many variables in trading which may influence how this plays out, but at the end of the day, its here folks, as a fact, however unpopular. It IS clearly enforceable, Hattons would not be complying otherwise.
However, all is not lost, with a choice of remaining suppliers Im sure most Aust modellers can find their needs met. Where Hattons stood out was postage charges, but if you bundle astutely with the some of the others they do not cost much more. Its not as though Hattons prices are that competitive against other UK suppliers these days anyway. And yes, we are all aware that they are still cheaper than local Australian retailers.
