If you still have things to buy for Christmas via the Web, consider making those purchases today. Today, Dec. 17, is Free Shipping Day. More than 700 online retailers have agreed to offer free shipping on all or some of their orders placed on this day. For details, visit www.freeshippingday.com.

Note that some of the stores’ free shipping offers are dependent on minimum purchase amounts, and some items are excluded from free shipping. Others require a coupon code; the Free Shipping Day website will have that information.

Here’s are some of the best free-shipping offers (in my opinion). I tried to find ones that had free shipping with few or no restrictions.

Overstock.com – free shipping on all orders, excluding media.
Pottery Barn – free shipping on all in-stock items, except furniture.
Sears – free shipping on orders over $39, plus receive $1 back on each item over $10.
Lady Bird Johnson Wildflower Center (wildflower.org) – free shipping on all orders.
Levi’s – free shipping on all orders.
Origins – free shipping on all orders.
Piperlime – free shipping on all orders.

Please note that if you buy something with free shipping and then need to return it, you may have to pay to ship it back. Check the return policies of each store before you buy.
