What Is It?

The **Order Bump Bias** is a psychological phenomenon in e-commerce and sales where a customer, having already committed to a primary purchase, is highly susceptible to adding a small, complementary, and low-friction offer—the "order bump"—to their cart just before completing the transaction. This bias leverages the psychological momentum of the initial commitment, making the small, additional decision feel insignificant in comparison to the larger one already made. It is distinct from an upsell, which typically replaces the original item with a more expensive one, or a cross-sell, which is often presented earlier in the shopping journey.

The effectiveness of the order bump lies in its placement and perceived value. By presenting the offer directly on the checkout page, the customer is already in a state of high commitment, having entered their payment details and mentally finalized the purchase. The order bump is typically a highly relevant, low-cost item (usually under 25% of the main product price) that requires only a single click to add. For example, a customer buying a $100 online course might be offered a $15 "Quick Start Checklist" or a "Bonus Template Pack" on the checkout page. The perceived value of the add-on is high, while the additional cost is low, making the decision to add it almost automatic and highly profitable for the seller, significantly increasing the Average Order Value (AOV) [1].

How It Works

The Order Bump Bias is driven by several core psychological mechanisms that converge at the point of purchase:

Mechanism/Theory Explanation
Commitment and Consistency Once a customer has made the significant decision to purchase the main product, they are psychologically committed to the transaction (Sunk Cost Bias). Adding a small, related item is seen as a consistent, minor extension of that primary decision, rather than a new, high-friction choice [2].
Anchoring and Contrast Principle The price of the order bump is anchored against the much larger price of the main purchase. A $20 add-on to a $200 purchase feels negligible (a 10% increase), whereas a $20 purchase on its own would require more deliberation. The contrast makes the bump seem like a small, easy win [3].
Impulse Buying and Frictionless Purchase The order bump is presented at the moment of highest buying intent, encouraging an emotional, impulse decision. The one-click, "check-the-box" mechanism removes all transactional friction, bypassing the rational part of the brain that might otherwise veto the purchase [4].
Perceived Scarcity and Urgency Order bumps are often framed as a "one-time offer" or "only available now," leveraging the principle of scarcity. This creates a fear of missing out (FOMO) on a highly relevant, discounted item, forcing an immediate decision before the opportunity is lost [5].

Quote from a Popular Marketer

“The order form bump is one of the most powerful things you can do to increase your average cart value. It's a small, relevant offer that they can add with a single click, and because they've already committed to the main purchase, the friction is almost zero.”

10 Tips on How to Use It in Marketing

  1. Ensure Extreme Relevance: The order bump must be a logical, complementary extension of the main product. For example, if selling a coffee maker, the bump should be a bag of specialty coffee beans or a descaling solution, not a pair of socks. This ensures the customer perceives the bump as a helpful addition, not a distraction.
  2. Price it Low (Under 25% of Main Product): The price point is critical. The bump should be low enough that it feels like an easy, "no-brainer" decision. A common rule is to keep the price under 25% of the main product's cost to maintain the psychological contrast and low-friction nature.
  3. Use a "Check-the-Box" Format: The mechanism for adding the bump must be a single, simple action, typically a checkbox on the final checkout page. Avoid requiring a new page load or re-entering payment information, as this reintroduces friction and breaks the commitment momentum.
  4. Offer a "Quick Win" or Immediate Benefit: The bump should promise an immediate solution or enhancement. Examples include a "Fast-Track Guide," "Installation Service," or "Bonus Template Pack." This appeals to the customer's desire for instant gratification.
  5. Frame it as a "One-Time Offer": Use scarcity language to emphasize that the offer is only available at this specific moment on the checkout page. Phrases like "Add this now and save 50%," or "Only available on this page" leverage FOMO and encourage an immediate decision.
  6. Highlight the Value, Not Just the Price: Clearly articulate the benefit and the perceived value of the bump. Instead of just "$19.99," say "Get the $50 Value Video Training for just $19.99—a 60% discount!" This reinforces the anchoring effect.
  7. Test Digital vs. Physical Bumps: Digital products (e.g., e-books, checklists, templates) often have a higher profit margin and lower fulfillment cost, making them ideal bumps. However, a small, highly relevant physical item (like a protective case for an electronic device) can also work well. A/B test both.
  8. Use Social Proof: Include a small line of text near the bump that says, "9 out of 10 customers who bought [Main Product] also added this," or "Most Popular Add-on." This leverages herd mentality to validate the decision.
  9. Avoid Offering Too Many Choices: Limit the order bump to one, or at most two, highly relevant options. Presenting too many choices can trigger the "Paradox of Choice," leading to decision paralysis and potentially causing the customer to abandon the entire cart.
  10. Track and Optimize AOV: The primary metric for success is the increase in Average Order Value (AOV). Continuously track the conversion rate of the order bump and the resulting AOV. Use this data to refine the offer, price, and placement for maximum profitability.
