how do you sell items ?

i have soo much junk like objects

 

Go to a shop and click on the "sell" tab?

 

the only shop i found is at outpost and i dont see a sell tab

 

Did you update to Pleased Giraffe? Because all the Outpost shops should have access to the "sell" feature.

 

im fairly sure i did all my weapons do like 15 damage tops

 

Then interact with the Infinity Express or Terra-Mart and look for any part of the interface that says "sell". Click that part.
