I sold an item in my shop for 1000000 sP and someone bought it, but it isn't showing up in my currency? Is it a glitch or what is going on?
It should be in your shop till, not your onhand currency. :)
Look at the navigation menu tabs toward the top of the page:
Go to Commerce > Your Shops > [click shop name] > Profits
From there, you can choose to take the sP out of your shop and carry it onhand by clicking the "Collect ___ sP" button.
Do keep in mind that you can get achievements from keeping a certain amount of sP in your shop till though :)
Also, you can alert people to the forums like I did for you by putting an @ in front of their username.
Feel free to ask if you have any other questions.
