Our club races with NIPA are 50p a bird inland, and it depends on the birdage when going to the channel so the crates charges are covered. NIMR is 25p a bird for all inland races except for the gold ring race that cost £5 to activate the ring.
I can only speak for the Tipes rings Dougie, but any faulty rings are returned to the rep K. Kernahan which in our circumstances doesn't require postage as he lives about 40mls from Derry and we have the rings replaced.
