the per-title costs, the per-copy costs and the payment fees.

With the illustration above and a fan price of 1,200 THB (an example,
not a recommendation) and payment fees of about 3.5%: break-even is

about **799 THB**, because the per-title cost spreads. The calculator
shows the artist this before launch, for any price they type in. Shipping
is charged to the fan separately at checkout, at cost.
