I checked
Line by Line Sales
You must specify the price of each line in case you check this option.
But I can only specify one price for all the lines (bug or ui error?), what if the game codes are for different games? How do I indicate the game for example line 1 or 2 without showing the keys?
I used it before, line by line sales are for licence keys, game codes, or any codes for a specific service, like NETFLIX for example, you paste 50 accounts like this:
email password
email password
email password
email password
email password
And when someone buy from you, he will get one line (Or one account) !
You specify price for each line or for each account
