The place where the members of an LLC (i.e. its owners) live is irrelevant. Foreign filing is required in states where the company does business.
Also, the mere fact that a company receives mail at an address does not itself establish that this is where the company is doing business.
If the person or people who carry out the work of an LLC organized in Wyoming actually do the work in Florida, it should foreign file in Florida. It may also want to foreign file in places where it sells its online products to customers, especially if it is foreseeable that it might need to sue (e.g. for nonpayment) someone in a state where customers are located.
