I was looking to buy one of these 12v triggers to power on a PA without a trigger input from audiophonics in France. Unfortunately, due to Brexit and customs, there is a €160 minimum these days and they are only €25 + tax and shipping.
The minimum I can buy to hit the €160 minimum (ex delivery) is seven. The total cost is €190 including tax and delivery, so €190.18/7 = €27.17 each ~ £24 each. Perhaps there will be customs charges, perhaps not. Clearly there would be a small onward delivery charge as well, but hopefully £25/£26 should be enough.
If anyone is interested in teaming up to reach seven items, then I'd be happy to organise.
