New requirement of "Commercial liability insurance" in EU from 29 may

Good day dear sellers, I think the news of mandatory insurance has overshadowed everyone without exception.

Please tell who has already had experience in obtaining such insurance, which companies did it for you and what is the price of the policy?

We are a company from the Czech Republic and the "best" offer we get is  €3,500 per year. It is more profitable for us to close our business.
