Hi, I have two questions about submitting a Custom Wearable.
Question number one: When you submit a custom wearable and you want it put straight to your shop, how does that work? For example if I want 10 copies in my shop. Do I have to pay for those 10 copies to get them in the shop or do the cost of those copies get off from the profit if I would sell them?
To hopefully help you out a bit, I'll answer what I can:
One: you have to pay for all ten copies yourself in that instance; you can have other people help you out by assigning slots of a designated price to help and give you a little profit. The slots, in the long run, are the more practical and profitable.
Two: you'll see the amount now when you go to submit it. The backgrounds cost the most at 5000 CSC and they go down from there. It used to be 5k CSC flat when I started out but now, depending on the size, it'll fluctuate quite a bit. (I.e. people were submitting tiny ring like things for 5k and that wasn't going well at all. Understandably.)

Actually, if you submit directly to the cash shop you only pay 1000 CSC + the minimum cost of one item (so, items that cost 5000 CSC per batch will cost 1600 to submit direct to the Cash Shop). You pay that cost once and you can put as many copies in your shop as you want. It's only if you want to have the 10 copies yourself that you would need to pay the full cost to submit a batch.
