What is the Ideal Profit Margin for Print-On-Demand Business

[Kane]

Print-On-Demand is a business model where you create a design and use your design on products and you sell your product. When someone buys your product, your supplier will manufacture your product and ship to the buyer. You pay a base price for every product your supplier makes and you add your profit margin. By the way what is the ideal profit margin? Well, I add 10-20 percent margin.
