This site is not built on theory.
It is built on decisions made while actively selling on eBay, Vinted and Etsy in the UK and building structured assets.
Case Studies documents:
- What was tested
- What capital was deployed
- What changed
- What held profit
- What was stopped
- What the numbers actually showed
These posts are operating records. Each one connects back to margin, sell-through, recovery speed or structural risk, not opinion.
They show which decisions improved income, which reduced friction, and which needed ending.
Marketplace Structure Decisions
Structural changes often affect income more than individual listings. The broader income model is outlined in How I Make Money on eBay, Vinted and Etsy.
When an eBay Listing Became an Asset
How one listing shifted from short-term activity to repeatable income.
Category Tests & Stopping Early
Not every category deserves capital.
Testing Golf Clubs as a Resale Category
A documented category trial measured against demand and margin.
What Happened When I Tried Flipping Golf Clubs, and Why I Stopped
An example of stopping early instead of forcing weak performance.
When eBay Stops Being Worth Your Time
Recognising when effort and return no longer justify continuation.
Inventory & Risk Decisions
Income starts at buying decisions.
These posts show how sourcing affects margin and exposure.
Are Clothing Bales Worth It? A Real Case Study
A 150kg wholesale outerwear test measured against margin, fees, demand and supplier stability.
What Vintage Leather Jackets Actually Sell For on eBay UK
Three leather jacket batches tested against entry price, sell-through, ROI and supplier risk. Real sales data showing where the £30–£45 recycler band holds and where higher tiers work.
Vintage Levi’s, Lee & Wrangler Shirts
Brand-driven vintage resale with predictable demand.
Vintage Unbranded Denim Jackets
Testing whether margin holds without recognised labels.
Vintage Leather Flying Jackets
Higher-ticket inventory and controlled risk.
Digital Build Decisions
Some assets are digital rather than physical.
The same rule applies: structure determines sustainability. The full digital engine is documented in Digital Products.
Building Info Product Build
A record of product decisions and constraint.
Updating a Product Without Breaking the Calm
Improving an asset without destabilising it.
Ending & Refining
Sometimes progress comes from removal.
Finishing Weekend Golfers
Ending a project cleanly rather than letting it drift.
Updating an Old Asset Instead of Starting Something New
Why refinement can outperform expansion.
Why This Section Exists
These posts show what changed performance and what didn’t.
Patterns become clearer when decisions are written down.
Clear patterns reduce repeated mistakes.
Reduced mistakes protect margin. If something stops justifying its structure, apply the tests in When to Stop.

Case Studies shows how those decisions evolved in practice. Some tests confirm the model. Others expose its limits. Both are recorded.
