That's where Luke Knowles' website comes in.
Knowles is the founder of freeshipping.org, a website that lists shipping codes and coupon offers from more than 800 online retailers.
Knowles gets a commission from retailers whenever shoppers use a shipping code from his website. Knowles says, "A lot of people are bargain-hunters. They will only shop if they think they're getting a deal. Free shipping can make the difference between making the sale and not making the sale."
That's why retailers want to be on the site.
They know shoppers will be quick to open a new browser window to see if they can get free shipping. If they can, they're more likely to make the online purchase they're thinking about.
On freeshipping.org, retailers are listed alphabetically and by the items in which they specialize.
Be warned though. Some of the retailers require you spend a certain amount before you can take advantage of the free shipping codes. So, it takes some will-power not to add items to your cart that you don't really need.
Knowles says the retailers know the amount of an average purchase, and often set a free shipping threshold just above that amount, to encourage you to put just one more item in your cart.
