📦Buying and reselling business ideas

Reselling has the lowest barrier to entry in the whole catalogue: buy low, sell higher. But the margin does not come from luck or from stumbling onto a clearance sale. It comes from knowing what a thing is worth before the seller does — and that knowledge either comes from a trade you already know, or you pay for it in mistakes.

There are 21 ideas here: thrift and second-hand selling, liquidation and returns pallets, retro electronics, furniture, collectibles. Each entry gives the capital required, the usual margin, the steps and the risks. The calculator accounts for what does not sell — and unsold stock is what decides whether this is a business or an expensive hobby.
