Calculating Delivery Dates

How are shipping and delivery dates calculated?

Our estimated shipping dates are based on several factors, including the destination address, the shipping options you've chosen, and how quickly we can obtain and assemble items for shipment (the availability time listed on a product's detail page). Also, orders for multiple items or multiple copies of a single item can take longer to assemble before we're able to ship them to you.

We calculate delivery estimates by taking the estimated shipping date and adding the transit time (the time it takes a package to travel from our facilities to your destination address), based on the shipping speed you've chosen.

For example, if you order an item that is listed as "Usually ships in 2-3 days" and select standard U.S. shipping (which typically has a transit time of 3-5 business days), you can determine that your order should arrive 5-8 business days after you place it.

International customers: When orders shipped internationally reach the destination country, they may be subject to customs clearance procedures which can cause delays beyond original delivery estimates.

Getting Items Faster

You can select a different shipping speed by clicking the radio button next to that option on the order form. Note that changing your shipping speed to a faster method will not change the estimated shipping date, but your estimated delivery date should improve (subject to item availability).

How One-Day Shipping Works

Not all of the items listed on our site are available immediately, so selecting Next Day or Second Day Shipping does not necessarily mean your order will arrive in one or two days. Saturday delivery is available for certain locations. Also, when you select Next Day or Second Day Shipping, we may use air or ground shipping as necessary to get your items to you within the promised time frame.
