This triple conjunction occurred, roughly (depending on the orbs you allow), between September 1987 and September 1990, a span of three years.
During this time the relationships of the three planets to each other were not the same; they changed over time. Sometimes one or even all three of the planets were retrograde, sometimes all direct, or only one or two of them retrograde. Saturn may have been earlier in the zodiac than the other two, or between them, or coming last. Aspects to the group changed. At times these planets were in two different signs while still in conjunction. The distances between them varied.
I happen to belong to the "What you see is what you get" school of astrology. The arrangement of things (in a triple conjunction, for example) is quite important in interpretation. Saturn applying to Uranus and Neptune is not at all the same as finding Saturn trapped between (besieged, under duress) the two planets, and perhaps retorgrade and afflicted by hard aspects to boot. Saturn separating from the other two is something else again.
I agree with Sworm09 in one thing, and that is that money is probably an important issue in your life. To say much more than that, as Sworm09 also says, demands looking at the whole chart and understanding the role of money (and other Second House matters) in the life. And of course, much depends on who is lord of the house as well. If it is Jupiter things become even more complex because there is an added factor.

No single horoscopic factor, or set of factors, can be understood except in the context of the chart as an integral whole.
