Why static pricing loses
If you set a price once and forget it, you're playing a different game than 43% of your competitors. The eBay marketplace shifts daily — competitor entry, supplier cost changes, demand spikes — and a static price is wrong within 30 days.

Avg. margin lift after rules
The 4 rules every dynamic pricing system needs
- 1
Hard margin floor
No matter what a competitor does, you don't sell below X% margin. Period. This is the wall that prevents a price war from destroying you.
- 2
Match-the-lowest with delta
Match the cheapest competitor's all-in price minus $0.10 — but only down to your floor. Above the floor, defend share. At the floor, walk away.
- 3
Time-of-day boost
Buyer behavior peaks Sunday evening and Monday morning. Raise prices 2–3% during peak windows when search volume is highest.
- 4
Stock-out advantage
When a top-3 competitor goes out of stock, raise your price 4–8% for the duration. Most sellers don't notice this window.
When to break the rules
Stick to the rules
- — Routine competitor undercuts
- — Seasonal demand swings
- — New listings in mature categories
- — Restocked SKUs
Override manually
- + Coordinated multi-competitor attack
- + Major supply chain disruption
- + Brand exclusivity windows
- + Liquidation/exit scenarios
Setup checklist
- Define A/B/C SKU tiers with separate floors
- Set 'react time' — how fast you respond to competitor moves (recommend: 4–6 hours)
- Configure all-in price tracking, not list price only
- Build a daily 'attack report' so you see patterns, not events
"Dynamic pricing is not a tool. It's a discipline. The tool just enforces the discipline you already decided on."
