Maybe it would be nice if price check would be Auto by seeing for how much other sold/bought items.
When some1 buying something they write what they bought and then if some1 needs to price check they can write item and see last sells on that item making it easy pricce check

Way too complicated to automate price checks. Would be nice in an ideal world but not realistic as a feature

there is sites that has it so i think thats possible

The problems I see with this,
1# People sell things cheaper to friends. So that will effect your automation prices.
2# Prices are not stable, depending on time of day prices flux.
3# Stats / rolls on items make a big difference in price so the automation would have to take every item in the game with every roll into consideration.

Maybe I am overthinking it but this is what came to mind

Terrible idea. Would distort bidding and the dynamic nature of selling items that could end up in a price range (which can be positively stimulating to the buyer and seller)

yea i understand thats just an idea just i see a lot of newbies (myself included ) gets lower prices because there is no efficient price check
