PriceTrail

PriceTrail watches Amazon UK product prices and pings you when they drop.

Drop in any Amazon UK link or paste an ASIN. PriceTrail starts checking the price for you on a schedule and keeps the full price history, so you can see at a glance whether £24 today is a real low or just yesterday's number. When the price changes, you get a notification — tap it to jump straight to that item's chart.

Each tracked product also shows every seller's current offer side-by-side. Amazon, Amazon Resale, third-party sellers, "New" copies and "Used – Like New" copies are all listed together, sorted cheapest first, so you can decide where to actually buy from.

• Push notifications when a tracked price changes • Per-seller breakdown with condition (New, Used - Good, …) shown alongside the price • Pull down on the chart to re-check a single item on demand • Hourly background polling — no manual taps needed • Star the items you care about most so they sit at the top • Built for Amazon UK
