Merchant value spreadsheet
 

I am considering putting together a spreadsheet formatted for printing with merchant values for various common drops like gems, Fine Steel and vendor jewelry. I often have to make decisions on what to keep when my bags are full and it would be nice to have a printable reference instead of having to look up values online individually.

If something like this already exists and you are willing to share please let me know, otherwise any input would be appreciated and I when I finish I will make it available here.

Allakhazam has merchant values for most items, I'm not sure what faction/charisma it's based off of, though.

I actually keep a personal record of all the vendor trash I sell along with race, class, charisma and faction con.

Then I ask other people what they sell the same item for.. it's not widely different in price but it is different enough sometimes that this information isn't universal.
Some things have been upwards of 9pp price difference(high end vendor trash).

That's a good idea :)
