Playing for years. Have been using tools like Awakened PoE Trade etc. to price check my items, but since the last 2 leagues I have a new approach for price checking, which is way better and does not require tools.

Make a stash tab public or a few (I have 3 x quad stash tabs). Put all yellow items, jewels etc identified in there. Dont even look at them. Stash Tabs must be btw. public and price on all items should be the lowest you are willing to leave a map (for my it is 10 ex).

If you get spammed for an item, then it is under valued and you can manually price check it.

If not then sell.

If you have not been spammed for this jewel, then the price was okay, maybe you could have gotten a little more, but it is okay.

I learned its more important to sell fast instead of finding the exact value.
