A cheap item is not a good buy. Buy the exit, not the bargain.
The sourcing question is not “could this sell for more?” It is “who buys this, at what realistic price, how quickly, and what is the most I can pay while still meeting my return target?”
Before buying, identify the item, check realistic sold evidence/current competition, estimate a conservative sale price, account for condition and costs, then calculate a maximum buy price.
If you cannot explain the likely buyer or the evidence for value, treat the purchase as a speculative learning buy and size the risk accordingly.
Use the 60-second sourcing filter.
Identity
Brand/model/era/material/size/licence: do you actually know what you are holding?
Demand
Can you find evidence that people buy this type of item, not merely list it?
Economics
What is the conservative sale value after condition adjustment, and what costs will sit between purchase and profit?
Velocity
Does your own history or market evidence suggest fast movement, seasonal movement or a long hold?
Downside
If you are wrong, can you recover most of the cost or are you buying a hard-to-clear problem?
Sourcing skill is pattern recognition plus numbers
The “eye” gets faster with repetition, but intuition becomes more valuable when it is checked against outcomes. Save which brands, categories, suppliers and price bands actually sold for you.
Condition is part of the buy price
A £100 clean sale does not make a stained £25 example a £50 buy. Cleaning time, repair risk and buyer resistance belong in the sourcing decision before money changes hands.
Rare does not mean liquid
Scarcity matters only when somebody wants the scarce thing. Low supply with almost no demand can be harder to sell than a common product with constant buyers.
Quick checklist
- Item identified
- Sold evidence found
- Current competition checked
- Condition cost/risk included
- Conservative sale price chosen
- Expected selling costs included
- Target profit chosen
- Maximum buy price calculated
- Likely selling speed considered
If the profit exists only at the highest sold comp and perfect condition, the buy is too dependent on optimism.
What should I look up first at a charity shop or car boot?
Start with exact identity: label, model/style code, era clues, material, size and condition. Then search sold evidence and current alternatives.
Is a high ROI item always a good buy?
No. A tiny-cost item can have high percentage ROI but low pound profit and poor sell-through. Consider profit, time, space and velocity together.
Should I buy rare vintage even if there are no sold comps?
Only with appropriate risk. Absence of comps can mean genuine scarcity or lack of demand. Use adjacent evidence and lower your confidence rather than inventing a value.
Turn the advice into a repeatable workflow.
Track stock age, cost, sale price, profit and marketplace activity instead of trying to remember it all.
