HOW ARE SHIPPING & DELIVERY DATES CALCULATED?

You'll see an estimated shipping or delivery date for each shipment on the order summary, just before you place your order. An estimated delivery date (or date range) will also appear in Your Orders after you've placed your order.
Delivery estimates are calculated 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. The transit time is calculated using business days, meaning Friday and Saturday don't count toward the transit time (unless we've specifically offered a weekend delivery during checkout). Holidays are also taken into account when calculating the transit time.

FREE Two-Day Shipping through ArabPTBook 
If the item you're ordering is out of stock or unavailable to ship immediately, you may not receive the item within two business days. Selecting One-Day or Two-Day Shipping will reduce the transit time to one or two business days after we've shipped your order, but it won't impact how long it takes us to obtain the item or prepare it for shipment. The shipping method time starts when the item ships. For example, it will take up to two business days after an item ships to reach you with Two-Day Shipping.

FREE Shipping (for free shipping coupon holders). 
Your order will be delivered within 2-4 business days. We process and ship your order in the most cost-efficient way possible so we can pass the savings on to you in the form of free shipping. If you look in Your Orders and see that your items haven't shipped yet, don't worry. We may take a little longer than you expect to ship out your order, but we won't delay shipping if it means we'll miss the expected delivery date.

Note: If you live in an area experiencing an unexpected service delay (severe weather, natural disasters, unscheduled events, etc.), please add at least 2 to 3 business days to the estimated delivery date of your order. In some cases, choosing a higher quantity of an item may make it ineligible for immediate shipping, because multiple units may not be available locally or at the same location. In this case, the option to choose One-Day Delivery may not appear.
