they can't insist on you buying your stuff from their supplier if it is not to the same standard + if an item is irreplaceable such as hand made rods they have to give you the money so for all you people with cakey's modified alarms you can insist on the cash as they cannot be bought.
just had a look at bosfish & the only thing they sell what i have is my alarms and brolly so they would have to stump up the cash: thats the law
