What's the endowment effect and how does it relate to discounts?

Question

I'm struggling to understand the psychological principle behind why people value items they already own more highly than identical items they don't possess. As an e-commerce professional, I want to know how this cognitive bias might impact my discount and pricing strategies. How can I leverage the endowment effect to increase conversions and customer perceived value without undermining my brand's pricing integrity?

Price Anchoring in Discount Campaigns: How to Use It Effectively
Price anchoring is one of the most powerful and well-documented pricing psychology techniques. When customers see a higher "original" price before a discounted price, the anchor makes the discounted price feel significantly more attractive - even if the percentage off is modest. Used correctly, anchoring lets you present the same discount as more valuable without changing the actual discount amount.

Anchoring Formats and Their Effectiveness

FormatExampleAnchor Strength

Strikethrough original price$120 $84High - visual contrast is immediate
RRP / MSRP anchorRRP $150, Our Price $99High - external authority anchor
Compare at priceCompare at $89, Now $67Medium - Shopify native, widely used
Bundle value anchorTotal value $200, Bundle price $129Very high - large numerical gap
Per-unit anchorUsually $3.50/unit, now $2.10/unitMedium - works for consumables

Anchoring Best Practices

The anchor must be a price you actually charged (not inflated for the sake of the discount) - FTC regulations require anchors be genuine
Larger font and muted color for anchor; bold and prominent color for discounted price
Show both $ savings and % off - different shoppers respond to different formats
Use the Rule of 100: show % off for prices under $100, $ amount off for prices over $100
Don't anchor on a price that's significantly higher than competitors - it damages trust

Growth Suite: Anchoring Plus Genuine Urgency
Growth Suite's High-Fidelity Countdown Timer pairs price anchoring with real time pressure. When the offer pop-up shows a visitor the original price struck through alongside the discounted price and a countdown timer, both psychological forces activate simultaneously: the anchor makes the discount feel valuable, and the timer makes acting now feel necessary. Because Growth Suite's timers expire server-side (the code is deleted when time runs out), the urgency is genuine - reinforcing rather than undermining the price anchor's credibility.
