Short answer
Designers should implement features that encourage thoughtful consideration and reduce the psychological triggers for impulse buying within sustainable marketplaces, such as adding 'add to wishlist' or 'save for later' options with clear time limits, or providing comparative sustainability impact information.

The design of second-hand online marketplaces, while intended to promote sustainable consumption, can inadvertently foster impulse buying due to immersive browsing experiences and perceived scarcity. This sustainability research insight is drawn from a 2025 study published in International Journal of Consumer Studies. Using Mixed-methods study combining quantitative surveys and qualitative interviews. with 684 survey respondents and 23 interview participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should implement features that encourage thoughtful consideration and reduce the psychological triggers for impulse buying within sustainable marketplaces, such as adding 'add to wishlist' or 'save for later' options with clear time limits, or providing comparative sustainability impact information.
Sustainable Consumption Paradox: Second-Hand Marketplaces Fuel Impulse Buys

Key Findings
- 01User immersive experience mediates the relationship between browsing and impulse buying.
- 02Serendipity, perceived scarcity, and deal proneness interact to influence impulse buying.
- 03Consumers' efforts to buy sustainably can be undermined by excessive impulsive behaviors on these platforms.
Application
Design takeaway
Designers should implement features that encourage thoughtful consideration and reduce the psychological triggers for impulse buying within sustainable marketplaces, such as adding 'add to wishlist' or 'save for later' options with clear time limits, or providing comparative sustainability impact information.
How to apply
When designing or redesigning platforms for second-hand goods, incorporate features that prompt users to pause and reflect before purchasing, such as 'Why do you want this item?' prompts or a brief cool-down period before checkout for high-value items.
Project actions
- 01Consider how the visual design and layout of a second-hand marketplace might encourage quick decisions.
- 02Explore how 'limited stock' indicators or 'flash sale' features impact user behavior in a design project.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a mixed-methods approach for a comprehensive understanding.
- +Investigates a novel context (Facebook second-hand marketplace) and its relation to sustainability.
Limitations
It can be challenging to isolate the effect of platform design from individual user traits like deal proneness or existing shopping habits.
Reliability & validity
The use of structural equation modeling and NVivo for qualitative analysis suggests a robust methodology. However, the reliance on self-reported data for impulse buying and the specific context of Facebook may limit generalizability.
Think critically
How can designers ethically balance the goal of promoting sustainable consumption with the commercial imperative to drive sales on second-hand marketplaces?
Design Principles
"Design for mindful consumption by balancing platform engagement with user awareness of purchasing intent."
Designers creating platforms for pre-owned goods need to be aware that their interface and features can influence user behavior beyond the intended goal of sustainability. Understanding these psychological triggers is crucial for developing responsible design strategies that genuinely support eco-conscious choices.
What This Means for Your Design
Online shops for used items can make people buy things they don't really need on impulse, even though they want to be eco-friendly. This happens because the way the shops are designed makes browsing fun and makes items seem rare or like good deals.

Paragraph starter
Research indicates that the design of online second-hand marketplaces can paradoxically encourage impulse buying, undermining sustainable consumption goals. Factors such as immersive browsing experiences, perceived scarcity, and deal proneness, amplified by platform features, contribute to this phenomenon (Husnain et al., 2025). Therefore, designers must carefully consider interface elements that promote mindful purchasing over impulsive acquisition.
