I suspect that Tesco may be taking things into their own hands (outwith MIC and GL) and so for white goods, for example, Tesco may have the supplier/manufacturers and or their own distribution centres containerize the goods and ship them via Mezeron. If they can get cheaper rates with Mezeron than IOMSPCo then they would be stupid not to use them. I can't see Tesco risking food shipments with Mezeron. At least they know there is a regular/scheduled service with IOMSPCo.
