Is there standard prices when selling items in chestshops to other players? If so, I would like to know so that I can match it
By going to other shops and getting their prices then get average price of the product and go for there.
Well running a successful shop is time consuming. Getting the right prices, Getting the materials and keeping your stock up by going collect material by yourself or buy from a supplier then sell higher to at least make a profit out of it then making sure you are not being bought out by other shops. Other idea's name your own price and see what members reaction to it if too high they will complain about it if to low they will buy all they can in one go.
