How to Check Demand on eBay Before Buying Inventory

The fastest way to lose money reselling DVDs is simple:

Buying first. Researching later.

In 2026, supply is massive.
Demand is selective.

You don’t guess.
You verify.

Step 1: Search the exact title

Be precise.

• Match format (DVD vs Blu-ray)
• Match region (Region 1, Region 4, etc.)
• Match edition (box set vs single disc)

Small differences change demand.

Step 2: Filter to “Sold Listings”

Click:

• Sold Items
• Sort by Recently Sold

Ignore unsold listings.

They do not represent demand.

Step 3: Compare active vs sold

Example:

• 200 active listings
• 60 sold (90 days)

That is roughly 30% sell-through — healthy demand.

If it is:

• 500 active
• 10 sold

That is oversupply.

This is how you estimate velocity.

Step 4: Watch for red flags

Avoid titles where:

• Sellers hold 20+ copies
• Hundreds of identical listings exist
• Only one outlier sale appears

High price does not equal strong demand.

The biggest mistake

Seeing:

“One sold for $29.99!”

Instead of asking:

“How many actually sold?”

Outliers create false confidence.

Consistent sales create reliable profit.

Bottom line

Before you buy, ask:

• Is demand real?
• Is velocity strong?
• Am I buying based on data or emotion?

The resellers who win in 2026 filter first.
