When listing an item to be sold through a market stand in the workshop, you can use the 'Check Item Listing' button on the right.
When you select 'Check Item Listing' button, you will find the item you wish to register for sale. You will be taken to a real-time sales list where you can directly check the market's lowest price.
Conversely, in the sales list of a specific item, you can click the 'Register Item' button. This allows you to immediately go to the sales registration screen for the item.
Utilize the two buttons appropriately to make the use of the market stand more convenient!
