Here they unload their small surplus and purchase minor amounts of farm equipment and luxuries for their barns and homes; some of their needs are already met through travelling pedlars and non-urban periodic fairs held at long intervals. Major producers - the great estates - would be attractive enough foci for merchants to consider travelling directly to purchase commercially-focussed harvests 'at the farm gate', and some landowners were wealthy enough to handle their own distribution to urban markets in the country of production and even to other countries. These latter processes are documented both in the ancient sources and archaeological case-studies."
