LOL. That's what you think. Once you get to higher levels (say me, approaching 50 on my rogue), cheap enchants are hard to come by, unless they are totally useless.
At your level of enchanting, the mats are like 50s to get. +15 agility, lifesteal, crusader O.O, +5 dmg to 1h, fiery, icy (which in my opinion suck since i'm a rogue), demon/beast slayer which almost never helps me are F*CKING EXPENSIVE!!!!
Beast/demonslayer - around 8g-10g per enchant
Fiery/Icy - 25g-35g
Agility - 70g on a good day
Crusader - 300g in mats plus 15g for enchanter
Lifesteal - i believe it is 90g per enchant
+5 dmg - No idea
But thats an overview of how expensive good enchants are.
