Have an online store?

If you DON'T have free shipping, you're missing a good bet.

Customers like it. It simplifies purchasing and seems like a discount (even though they know that the shipping charge is built into the item price).

Amazon, by far the largest online retailer (more than 10% of all online sales in North America) gives free shipping on almost all orders (just spend $25).

Is free shipping common? How about almost 50%:
