Hi there, @jonmc1 !
That is an interesting question for sure!
I had a look around for any possible matches for your query, and I was able to find an insurance provider in the UK that offers Shopify sellers’ insurance.
I also found another provider that specifically offers dropshipping insurance, though this one is not geared specifically toward Shopify.
As these are external, third-party services you would need to contact them directly for confirmation of their coverage, policies, and costs.
Could you tell me a bit more about your business and what you’re selling?
Are you engaging in dropshipping currently, or looking to do so in the future?
