PostNet vs St. Brendan's Isle: overview
PostNet
PostNet's virtual mailbox plans work differently from a typical marketplace or direct operator: each of its more than 100 US and Canada locations is a locally owned, independently run franchise, so pricing and service specifics genuinely vary center to center. Steve Greenbaum and Brian Spindel founded the company in 1992, and its core business has always been the physical retail center, printing, shipping, design, notary, and shredding, with the virtual mailbox as one plan among several offered at each location. Entry-level plans start around $9.99/mo, though the exact figure depends on which local center a customer signs up with.
St. Brendan's Isle
Rather than tiered plans, St. Brendan's Isle runs a single month-to-month service structure with an inactive-status feature that lets a customer pause billing without losing their address, useful for anyone who travels only part of the year. It began in Green Cove Springs, Florida in 1988 as a mail-forwarding service for live-aboard cruisers, and has grown to more than 3,500 clients worldwide without ever adding annual dues or a sign-up fee. The plan includes a genuine street address but stops there: no DMV packet, no Declaration of Domicile filing, no registered-agent service.
