My words literally betray me.
The descriptions for these are:
Marketers: Each barrel exported during this Export Action is with +1 VP
Salesmen: Each barrel sold in this Sales Action earns you +1 Bago.
Trying to determine if the tile give you an extra Sales/Export action that has the bonus? Or does the tile need to be played in combination with the appropriate action on the Quadrel (or via a Magnate tile)?
I am leaning toward the latter since the Magnate tiles explicitly say Perform the specified action.
Normally the experts adjusted actions (of course this only applied to one expert).(the 1 that gives you a discount of 1 on vineyards is during a vineyard action.)
But I don't have the rules in front of me for marketers or salesmen to specifically try to verify.
