Another Diablo 2 question

One of the more amateur mistakes in making money in Diablo II is that people seem to always consider that Unique > Set > Rare and everything else is NPC fodder. There are a lot of White/Socketed/Ethereal non-magical items that can be worth holding on to for selling purposes because Rune Words can be made in them, and even the odd blue Magical Item can be worth something if it has the right pre/suffixes, though these are more difficult to identify and find buyers for. You should keep this in mind for when you're playing through games.
