What a discount costs you if it goes wrong

Comparing two prices is easy. Comparing two offers is harder, because the price is only the part that is advertised. What happens when the item arrives damaged, stops working in a year, or simply is not what you expected varies enormously between sellers, and that variation is worth real money.

The return window is not standard

Return periods differ by retailer, by category, and often by whether the seller is the retailer itself or a marketplace third party on the same site. Some categories are excluded entirely. A slightly better price from a seller with a short window, a restocking fee, and buyer-paid return shipping can easily be the worse offer.

Who is actually selling it

On any marketplace, the retailer whose name is on the website may not be the party you are buying from. This changes the return process, who pays for it, and how disputes are resolved. It is the single most useful thing to check before buying from an unfamiliar listing at an unusually good price.

Warranty questions that matter

• Is the warranty from the manufacturer or the seller? Third-party warranties are only as good as the party behind them.
• Does the warranty survive if the item was bought from an unauthorised seller? For some brands it does not.
• Who pays shipping for a warranty claim, and does the clock start at purchase or delivery?
• Is a proof of purchase required in a form the seller will actually provide?

Protection plans are a separate purchase

Extended protection sold at checkout should be evaluated on its own, not folded into the deal. Ask what it covers beyond the manufacturer warranty already in place, what the excess is, and whether it repairs or replaces. Frequently the answer makes it poor value on a discounted item, because the payout is capped near what you paid rather than what the item is worth.

A short pre-purchase checklist

• Who is the seller, and what is their return window?
• Who pays return shipping, and is there a restocking fee?
• Who provides the warranty, and for how long?
• Is the total at checkout, including delivery, still a good price?
