One festival weekend out of state can trigger sales tax nexus. Register first, collect the combined rate, and reconcile the gross 1099-K on Schedule C.
A museum crate often costs more than the miles it travels — cost builds like manufacturing jobs and price transport per mile, or one subsidizes the other.
Skateboard decks earn 30-40% margin while accessories hit 50-65% — track each category's COGS separately or every buying decision is half-blind.
