DeliveryMan said "You get a mailbox and there isn’t much they can’t accommodate. It’s also an actual address like unit 38 1300 18th that you can use. FLEX POST doesn’t work for all carriers, mostly Canada Post and purolater (they’re owned by Canada post). Anything coming UPS/FedEx or DHL/Loomis will get bounced (except the very very rare shipments that come DHL/FedEx/UPS via Canada post). "
Thanks so much for the detailed info. This is exactly what I'm looking for.
