Chatting to the in-law earlier, he owns a small shop online, photography.
Two weeks ago, they shipped one of their cameras to France for £8.95, today they shipped the same model to France and it cost £15.60, using the same service as well as having to complete an extra customs declaration form.
As a small business, selling a niche product, it’s difficult for them to pass on the costs, or absorb them ( they ship around 18 cameras per week, plus other products they manufacture), so you’ll have to forgive them if they don’t celebrate the great new opportunities.
One example, sure many other experiences will follow.
Happy Brexit!
