We ship orders Monday through Friday and follow standard FedEx shipping schedules for 2 day shipping. FedEx begins counting shipping days the day after the package is handed off, and delivery timing is based on business days and FedEx service availability. For example, orders shipped on Thursday typically arrive the following Monday, and orders shipped on Friday typically arrive the following Tuesday. Weekend delivery may vary by location and FedEx service type.
While we cannot control FedEx transit times once a package is in their network, we do guarantee that qualifying orders placed before our daily 3 PM EST cutoff will ship the same business day
