Computey vs eBay vs Facebook Marketplace

A practical UK comparison of Computey, eBay, and Facebook Marketplace for buying and selling used PC parts: audience, protection, and logistics.
Current methods to buy and sell tech and electronics are dominated by generic platforms that have highly layered fees and poor structuring. Sellers lose margin, buyers overpay, and the market remains inefficient, and more importantly: underserved.
The UK’s secondary market for computer hardware and electronics is large, growing, and fundamentally inefficient.
Demand is rising. Supply exists. Transactions are happening.
But the infrastructure underneath it is flawed.
The majority of activity is captured by general marketplaces that were never designed for technology resale. As a result, pricing, trust, and liquidity are all distorted.
This isn’t a temporary inefficiency.
It’s structural.
Platforms like eBay and Amazon dominate resale volume.
Not because they are optimal.
Because they are default.
These platforms operate with layered fee structures:
• Listing fees and limits
• Editing fees
• Final value fees
• Monthly seller fees
• Payment processing fees
• Promotional / visibility fees
Individually, each fee looks manageable.
Combined, they compound.
This creates a system where:
• Sellers lose margin
• Prices are artificially inflated
• Buyers absorb the cost indirectly
General marketplaces effectively control pricing through these layered fees.
There’s no mystery here.
When sellers are charged more, they increase prices.
Not because they want to.
Because they have to.
The result:
This is particularly damaging in tech resale, where:
• Hardware depreciates quickly
• Pricing is highly competitive
• Buyers are extremely price-sensitive
Costs imposed on sellers are directly passed to buyers, reinforcing inefficiency across the entire market .
Everyone feels it. No one fixes it.
This is where things really fall apart.
Technology resale is not comparable to:
• Clothing
• Furniture
• General second-hand goods
It requires:
• Structured listings (specs, compatibility, condition)
• Trust signals (verification, testing, grading)
• Category-specific search and filtering
General marketplaces don’t provide this.
Because they aren’t built for it.
No platform is designed specifically for computer hardware and electronics; the market remains structurally underserved
So what happens?
• Listings become inconsistent
• Buyers lose confidence
• Sellers struggle to differentiate
The market fragments.
Globally, the secondary electronics market exceeds $100B+ and continues to grow.
Growth drivers are obvious:
• Rising cost of new hardware
• Supply chain constraints
• Cultural shift toward reuse and sustainability
And yet:
There is no global specialist platform for technology resale.
Other categories already solved this.
Fashion has Vinted.
Luxury has dedicated marketplaces.
Technology?
Still stuck on generic platforms and fragmented P2P channels.
That gap is not theoretical.
It just seems operational at this point.
Markets don’t stay inefficient forever.
They get replaced.
The replacement model is already clear:
1. Vertical Specialisation - A platform built specifically for:
• Computer hardware
• Electronics
• Structured product data
2. Transparent Fee Structures - A flat, predictable commission model:
• No stacked fees
• No hidden margin erosion
• Transparent ~10% commission model
3. Supply-Side Liquidity First - Real inventory from:
• Refurbishers
• Retailers
• Distributors
Not just casual sellers.
4. Infrastructure Ownership
Proprietary systems.
Not stitched together with third-party dependencies.
Because control over infrastructure = control over margin.
The market is moving, whether incumbents like it or not.
What used to be:
“sell your old tech”
Is becoming:
“operate a resale channel”
That requires different infrastructure.
The UK secondary tech market isn’t broken because demand is weak.
It’s broken because the infrastructure was never designed for it.
General marketplaces filled the gap by default.
Not by design.
And default solutions don’t last forever.
