Short answer
Do not try to price every drop. Triage items by build relevance, base type, useful affix combinations, required level, and whether there is actual trade demand. A fast decision flow is more useful than perfect price knowledge.
| Decision | Keep looking if | Move on if |
|---|---|---|
| Build relevance | It matches a popular skill, weapon, or defense need. | It has random stats with no clear user. |
| Base quality | The base type is desirable for current builds. | The base is weak for its level or slot. |
| Affix group | Several useful stats work together. | Good stats fight each other or support no plan. |
| Liquidity | Similar items appear to sell. | Only fantasy listings exist. |
| Personal use | It improves your current build now. | It would sit in stash indefinitely. |
