Prices listed in the thread of account sales, support. From the aspect of a new user who may have stumbled upon this site, it could be very discouraging seeing you have to click this link to discord, click this button to verify your discord in that discord server and then majority of the time the account isn't even listed within the server, let alone the price. So now you have to open a ticket, wait for a response, just to find out the account may be out of your budget. That is NOT buyer friendly of the slightest.
Grocery stores dont have "see price at checkout" listed on every item in the store.
As far as gold buying/selling and services, no support. As others have stated, prices change too often
