What to do with low value orbs?

Thank you all I'll follow your suggestions.

transmutation: use it on good white belt, ring, jewelry, maps. use it on weapon too if your weapon is bad.
alteration: roll a weapon with it at high lvl, roll maps, convert to fusing / jews.
augmentation: augment maps with them or any good blue gear.
chromatic: save up for coloring

if you ever need wisdom scrolls vender transmutation for them.

I trade low level orbs in mass for Chaos orbs. Then trade chaos for exalts, or use them to craft. If you do indeed craft...

You can burn through a ton of trans/alts/augs just to get 2 top tier stats on a white item.

I can only speculate how many people have left crazy good blue items on the ground or sold them unidentified.
