Brexit as commercial opportunity

Surely Brexit is an opportunity for many businesses? Following significant events, I often receive e-mails offering me relevant products and services, though relevance can be quite tenuous at times. I find such e-mails intriguing, because they are an attempt to make sense of what happened and outline future prospects while profiting from it. As Brexit is now a reality, there are many competing narratives as well as hopes and anxieties, which businesses can exploit. So far, the only Brexit-as-a-commercial-opportunity e-mail I received came from Yale University Press. Some of the titles look pretty interesting. NB: The image has been redacted slightly.
