Shipping & Returns


$4.99 flat rate shipping is limited to our continental U.S. customers only. Flat rate shipping method will be either USPS, UPS or FedEx. If you need a specific carrier, do not choose flat rate shipping, instead choose your preferred carrier at checkout. 

Standard shipping time is 3-5 business days, depending on the destination.

When choosing a shipping method, please note that delivery times listed are estimates provided by the carrier (FedEx, DHL, USPS, UPS) and do not include weekends, holidays or our handling time. However, most in stock items will ship within 24 hours (excluding weekends and holidays). 


An order can be canceled anytime before it is shipped. Once an order ships, it cannot be canceled and will instead need to be returned according to our return policy below.

Our goal is to process all orders in less than 24 hours. Most orders placed before 11am weekdays will ship the same day, so if you would like to change or cancel your order, please contact us as soon as possible and we will do our best to accommodate.
