When people start selling on eBay, they usually focus on:
- What to sell
- How to list
- How to ship
But one of the fastest ways to improve is simpler:
Avoid the mistakes that cost time and money.
I’ve made plenty of them — and still catch myself making some of them.
Mistake #1: Trying to Squeeze Every Dollar Out of an Item
Early on (and even sometimes now), I catch myself doing this.
Trying to:
- Get the absolute max price
- Hold out for the “perfect buyer”
But here’s the reality:
Time is money.
You can:
- Price high → wait months
- Or price competitively → sell in a week or two
What I do now:
- Price to sell
- Stay competitive
- Keep inventory moving
Faster sales > perfect sales
Mistake #2: Listing Items as “Used” When They Weren’t Fully Working
This is a big one — even if I personally didn’t do it often, a lot of sellers do.
eBay defines “Used” as:
– Fully operational and functions as intended
But many listings don’t follow that.
The problem:
- Buyers expect everything to work
- Even small issues can trigger returns
And here’s the bigger issue:
Buyers often don’t read descriptions.
What I do now:
If it’s not fully working:
– I list it as For Parts / Not Working
Even if:
- It turns on
- Mostly works
- Just has a weak battery
Important note:
You can list something as used with a small issue like:
- Weak battery
But ONLY if:
- It’s clearly stated
- Ideally mentioned in the title
Because if it’s buried in the description:
– You can still get a return
Reality:
I get messages all the time asking things that are already in the description.
That’s just how it is.
But you should still write one:
- Some buyers DO read it
- It protects you if issues come up
Mistake #3: Not Setting Clear Expectations
This is one I’ve always done, but it’s something you get better at over time.
What I do now:
I clearly say:
- What works
- What doesn’t
- What I didn’t test
On certain listings, I’ll even add:
“READ” in the title
– This helps signal to buyers:
“Look at the condition notes”
Real Example (Why This Matters)
I recently sold an item listed as “For Parts / Not Working.”
I clearly described:
- What didn’t work
- What I didn’t test
The buyer left positive feedback saying:
“Great deal and price. Unfortunately I wasn’t able to get anything working, but that’s my fault, not the seller.”
That’s exactly what you want.
The expectation was set correctly.
Mistake #4: Overthinking Listings
I still do this sometimes.
Spending too much time on:
- Descriptions
- Photos
- Getting everything perfect
The reality:
- Most buyers don’t read everything
- You don’t need perfection
What I do now:
- Keep it simple
- Take enough photos (not 20 of every angle)
- Move on
Instead of:
- 3–4 listings per hour
You should aim for:
– 8+ when you’re in a good flow
Mistake #5: Not Checking Sold Listings
This is one of the biggest beginner mistakes.
Two parts to this:
1. Buying without checking sold listings
You might buy something because:
- It looks valuable
- It seems rare
But:
– It might not actually sell
2. Listing without checking sold listings
If you don’t check:
- How do you price it?
- How do you stay competitive?
What I do now:
I always check both:
- Sold listings
- Active listings
Simple rule:
Sold listings should be equal to or higher than active listings
– That means stronger demand
Mistake #6: Underestimating Big Items
I didn’t realize this at first.
Then I sold a big item and thought:
“Wait… I need a massive box for this?”
The problem:
- Bigger boxes
- More packing material
- More time
- Higher shipping cost
What I do now:
I focus mostly on:
- Smaller items
- Lightweight items
- Easy-to-ship items
Unless:
👉 It’s a high-value item worth the hassle
Mistake #7: Trying to Do Everything Perfectly
I still catch myself doing this.
Trying to get:
- Perfect lighting
- Perfect focus
- Perfect photos
The reality:
There’s a balance.
- Some people need to do MORE
- Some people need to do LESS
What I do now:
- If you’re a perfectionist → do less
- If you’re sloppy → do more
Look at what actually sells:
- Not dark, bad photos
- But also not overproduced perfection
Final Thought
If you’re trying to figure out what sells on eBay or how to test electronics, mistakes are part of the process.
But avoiding the common ones will save you:
- Time
- Money
- Frustration
You don’t need to be perfect. You just need to keep moving.
