If someone stops paying, they're required to return their artwork (we even used to frame the relationship as a "rental"). In the case of a truly bad actor that stops paying and goes MIA, we make sure the artist gets paid, even if it's a loss for us.

For now, we charge a flat price for domestic shipping (with two tiers based on parcel size.) A near/medium-term goal is to integrate with shipping APIs for more nuanced shipping prices.
