Price comparison shopping has never been more important — or more powerful. With prices varying by hundreds of pounds for the same product across different platforms, knowing where to look can save you a significant amount every year. This guide covers everything.
The Big Three UK Marketplaces
Amazon UK
Best for: new products, fast delivery, Prime subscribers. Amazon's prices on new electronics and household goods are hard to beat, especially during Prime Day and Black Friday. The Renewed (refurbished) section is also excellent for certified used products with warranty coverage.
eBay UK
Best for: used items, collectibles, niche products. eBay's buyer protection is excellent and the sheer volume of listings means prices are genuinely competitive. The auction format can yield incredible deals — setting a max bid and waiting often beats Buy It Now prices.
Vinted UK
Best for: fashion, clothing, shoes. Vinted dominates second-hand fashion worldwide with over 8 million users. For branded clothing and trainers especially, prices are consistently lower than eBay — though buyer protection is less robust for high-value items.
When to Buy New vs Used
A rough guide:
- Buy new: items where condition matters a lot (mattresses, headphones with hygiene concerns, safety equipment), items under £30 where the saving isn't significant, or items where the warranty is important
- Buy used: electronics, books, games, tools, kitchen appliances, sports equipment, musical instruments — anything durable where condition can be assessed from photos
Price Tracking — Set Alerts and Wait
Prices on Amazon and eBay fluctuate constantly. For non-urgent purchases, set a price alert and wait. Amazon regularly drops prices by 20–30% during sales events. CheapestFinder's price tracker feature lets you set a target price and get emailed when any listing hits it across all three stores.
Timing Your Purchase
- Black Friday (November) — best time for new electronics across Amazon and eBay
- January sales — good for home goods and fashion, excellent for used items as people declutter
- End of summer (August–September) — great for outdoor equipment, garden furniture, bikes
- After Christmas — January is peak time for used gaming consoles as people sell unwanted gifts
Hidden Costs to Always Check
- Delivery charges — a £5 item with £4.99 postage isn't a bargain. Always check total cost
- Return policy — Amazon is excellent; eBay varies by seller; Vinted has buyer protection but returns can be harder
- Seller location — items shipping from China can take 4–6 weeks and may attract customs charges for items over £135
Use CheapestFinder for One-Search Comparison
