Saradomin armour sets are made by exchanging all the components of a set of Saradomin armor with a Grand Exchange clerk. Players can then exchange the set with a Grand Exchange clerk to receive the items individual items. The set is purely to save space and for use in the Grand Exchange.
The Saradomin armour set is considered to be a symbol of wealth among Free-to-Play players, as it is simply a trimmed variant of rune armour, and provides the exact same bonuses as a Rune armour set (l) or a Rune armour set (sk), though many players believe it looks much better. It is the most expensive free-to-play item which is not discontinued.
The Saradomin armour set (sk) is significantly cheaper than the (l) variety, because the demand for Saradomin platelegs is much higher than that for the Saradomin plateskirt despite the fact that they give the same bonuses, and despite the fact that the Saradomin plateskirt is actually lighter than platelegs.
