Core Rules

1. Research Sold Listings First

Before pricing: search eBay sold listings (filter: Sold Items).

  • Use exact model numbers, not generic terms
  • Note condition, included accessories, shipping method
  • Price range matters more than single data points

2. Title Optimization (80 chars max)

[Brand] [Model] [Specs] [Condition] [Key Features] [Accessories]
  • Front-load searchable terms
  • No filler words (WOW, LOOK, L@@K)
  • Include model numbers, not just names
  • Color and size if applicable

3. Fee Calculation

eBay fees structure:

Category Final Value Fee
Most categories 13.25%
Clothing 12%
Guitars 6%
Heavy Equipment 3%

Plus: $0.30 per order. PayPal/managed payments: ~2.9% + $0.30. Quick estimate: Take 15-17% off sale price for net profit.

4. Auction vs Buy It Now

Use Auction When Use BIN When
Rare/collectible items Common items with clear market price
Uncertain market value Need guaranteed price
Time-sensitive (holiday) High-value items (>$500)
Building feedback Consistent inventory

5. Shipping Strategy

  • Free shipping converts better but price it in
  • Calculated shipping for heavy/bulky items
  • Always add handling time buffer (1 day minimum)
  • Pack BEFORE listing to know exact dimensions

6. Scam Detection (Seller Side)

Red flags from buyers:

  • Requests to ship to different address than PayPal
  • "Can you end listing early for $X?"
  • Overpayment + request to wire difference
  • Pressure for tracking before payment clears
  • New account with shipping to freight forwarder

7. Scam Detection (Buyer Side)

Red flags from sellers:

  • Price too good to be true (50%+ below market)
  • Stock photos only
  • Ships from different country than stated
  • No returns, vague description, low feedback
  • Requests payment outside eBay

8. Return Policy Impact

Policy Effect
30-day free returns Higher search ranking, more sales
No returns Lower visibility, buyers more cautious
Restocking fee Legal but reduces conversions

Recommendation: 30-day returns for most items (rarely actually used).

Common Traps

  • Underestimating shipping โ†’ eat costs on heavy items; weigh and measure BEFORE listing
  • Ignoring item specifics โ†’ listings without specs get buried in search
  • Accepting PayPal without verification โ†’ chargebacks on high-value items; require signature for >$750
  • Pricing from asking, not sold โ†’ unsold listings don't reflect market; filter by SOLD
  • Shipping before payment clears โ†’ "Item Not Received" claims; wait for funds
