Products typically ship out between the same day and 1-3 days. Depending on the time/day ordered and the product type. Some products are made to order to spec and will ship once built. Feel free to call us at 704-871-0721 if you have any questions about shipping. Also call us if you are ordering large items like race car bodies as those are hard for the freight system to calculate sometimes and it will overestimate. Thank you.
