Research gives you the assumptions. These free tools help you turn those assumptions into a buying decision.
Know Your Buying Ceiling Before You Negotiate
The purchase price is one of the few major numbers you can control before the item enters your inventory. Work backwards rather than deciding emotionally.
Different Places. The Same Buying Discipline.
Where you source changes the type of opportunity you find, but the basic decision stays the same: research the item and make sure the numbers work.
Charity Shops
Useful for one-off second-hand finds where condition, brand, demand and buying price can vary significantly.
Check a Charity Shop Find →Car Boot Sales
Negotiation can create attractive buying opportunities, but condition and demand still need checking before you commit.
Set Your Negotiating Limit →Local Marketplaces
Local collections can open larger-item and bundle opportunities where postage may otherwise make the economics difficult.
Explore Marketplace Resources →Retail Clearance
Discounts alone do not guarantee resale demand. Compare realistic selling prices and all costs before buying multiples.
Check the Potential ROI →Wholesale
Buying larger quantities raises the importance of demand, cash flow, sell-through and the total amount of capital tied up in stock.
Model the Profit →Online Sourcing
Convenient access to more stock also means more competition. Account for delivery, condition risk and realistic resale value.
Learn the Sourcing Process →Cheap Doesn’t Automatically Mean Profitable
A low purchase price can still produce a poor result if demand is weak, the achievable selling price is low or fulfilment costs consume most of the margin.
Judge the complete opportunity rather than the price written on the charity shop label.
