All orders need time to be processed before shipment. General processing times are between 3-5 business days, though may increase during busy shopping or sale times. The customer may choose between different shipping methods based on how quickly they prefer the package be delivered. We feature UPS and USPS as our primary courier services. All delivery times presented at checkout are estimates provided by the couriers and are not guaranteed.
Keep in mind that all orders placed during non-business hours, including weekends, evenings and holidays, will not be processed until regular business hours have resumed, which are between Monday-Friday 10:00 AM - 6:00 PM EST.
If selecting USPS for shipping, keep in mind that their transit times are not guaranteed, meaning Priority 2 Day may take as much as 4 business days for delivery with no recourse from USPS.
If you have any further inquiries, please contact our Customer Service Department anytime Monday through Friday, 10:00am to 6:00pm EST.
