Free Shipping: A Modern Siren’s Song

A 17-inch rectangular HDPE outdoor side table arrived on our doorstep a few days ago, shipped at no cost to us. To me, this little side table is more than merely something to set things on; it is emblematic of a nefarious online sales tactic that has grown to mythic proportions. And I say “mythic” for good reason. I’ll try to explain.

Online shopping has reached mammoth levels in the US. The US Census caluculated that e-commerce sales for 2024 topped $1,192 billion (that’s $1.19 trillion!). Furthermore, on average each US resident received 66 parcels in 2024, which translates to an average of 167 packages on each household doorstep in the country. And from all indicators, e-commerce deliveries will continue to soar (you can find more detailed shipping statistics at sellerscommerce.com).

Given the volume of delivery vehicles making their way down the dusty road to our house here in Glen Ellen, I’m guessing that Ann and I score well above the average in the parcel-delivery department. It’s gotten to the point where Wynn, our Corgi, can hardly contain herself when she spots a delivery truck approaching. She has actually formed a bond with some of the drivers who slip her a treats when they drop off parcels.

You would think that would make us seasoned and savvy online shoppers. While “seasoned” may be accurate, the “savvy” part is questionable, especially when it comes to understanding the “free shipping” option.

Being skeptical of for-profit businesses that offer anything free, I decided to do a little research to get a handle on the “free shipping” option. After sifting through a ton of material and considering the social, psychological, and economic dimensions of the e-commerce free shipping phenomenon, it occurred to me that the lure of free shipping is not unlike what Odysseus faced with those scary mythical Sirens. To refresh your memory here’s a brief summary of Odysseus’ experience that was posted on the Audubon Magazine web site:

Odysseus, warned by the enchantress Circe of the danger posed by the Sirens’ song, orders his crew to stuff their ears with wax. But, curious to a fault, he has himself bound to the ship’s mast so he can listen without flinging himself into the sea. The Sirens promise him tales of all that had occurred during the war at Troy, and everywhere else besides; enchanted, he begs his crew to release him. He rants, raves, and threatens, but to no avail. His crew sails on until the song fades in the distance, and so saves his life.

[Editor’s note: The Audubon Magazine’s interest in this myth was undoubtedly inspired by the fact that the Sirens had the bodies of birds. Even so, Cornell’s Merlin Bird ID app does not include a Siren species — I checked.]

My point is that “free shipping” is like a Siren’s song – it ‘s seductive and can lure us onto the treacherous rocks of e-commerce by numbing the practical side of our brains and prompting us to irrationally hit that “Place Your Order” button on our digital shopping carts. There’s good reason to think this.

For one thing, take a look at these consumer survey results (from sellerscommerce.com) :

• 81% cite free shipping as their top delivery priority
• 75% prioritize free shipping over fast shipping
• 93% shop specifically to qualify for free shipping
• 70% abandon carts due to shipping costs

These numbers leave no doubt that the lure of free shipping is a huge consumer magnet for the 1.19 trillion dollar online shopping industry. But what is it about free shipping that’s so appealing?

A recent article by Adrian R. Camilleri, a marketing scholar at the University of Technology Sydney, offers some insights into why the free delivery option is such sweet music to consumers. He points out that the idea of “free” is uniquely attractive: “in behavioral economics, zero is not just a lower price; it flips a psychological switch” (emphasis added). Evidently, the prospect of getting something free produces a positive emotion which can lead us to consider the offer to be more valuable than it is mathematically — which may explain why 93% of consumers shop specifically for free shipping!

But what really hit home for me was Camilleri’s analysis of the free shipping threshold, a common e-marketing tactic. He provides an hypothetical scenario using a $55 threshold to illustrate the effect shipping thresholds have on potential consmers:

If your shopping cart is sitting at $40, you face a dilemma. You can pay $10 for postage, or you can find a $15 item to reach the ($55) threshold. Many of us choose the latter, reasoning it is better to get a tangible product, such as a pair of socks, than to “waste” money on shipping.

Retailers use this tactic because it evokes something called the “goal gradient effect,” the tendency to intensify our efforts the closer we get to a goal, which In this case is to reach a cart total of $55. If one pair of socks gets us close but doesn’t get us to the threshold, we are highly motivated to throw a second pair of socks into the cart, even if there’s already a drawerful in our bedroom.

I can do better than provide a hypothetical example by returning to that little side table I mentioned at the beginning of this blog. Purchasing that table was the outcome of Ann’s online search for a particular tea towel holder for our kitchen (it’s a long story). When she finally found the “right one” she discovered it was one cent (yes, one cent) below a $35 free shipping threshold. Her below text to me says it all:

I didn’t have the heart to tell her that she had just been seduced by a Siren’s song and was lured into the dreaded grip of the goal gradient effect. But I must grudgingly admit that getting 69 percent off is a hell of a bargain. Now if we can only figure out what to do with the table.

Before closing, let me warn you that free shipping is not the only seductive song in the e-commerce Sirens’ hymnal. Equally scary is the alluring “free returns” song.

But that’s another topic for another time. Happy online shopping.
