How we track prices

The exact rules The Ledger uses to decide whether a fragrance price drop is real, and how each product's price history is built.

Every drop on The Ledger is chosen by the same published rules. No one picks favourites, and no brand can pay to appear.

Where prices come from

Prices come from official product feeds supplied by UK retailers through affiliate networks. These feeds list each product's current price, stock status and product page. We read them once every morning.

How a drop is decided

An item appears as a drop only when all of these are true:

1. It is in stock at that retailer.
2. It is at least 10% below its own 30-day median price at that retailer. We compare against what the item has actually sold for recently, not the retailer's "was" or RRP price, which can be inflated.
3. The saving is at least £5, so tiny movements on cheaper bottles don't clutter the list.
4. We haven't already announced that price (or a lower one) in the past 30 days. You only hear about a deal once, unless it gets better.

Drops are ranked by percentage saving. Ties go to items at the lowest price we have ever recorded.

"Lowest price we've tracked"

This label means today's price is the lowest we have recorded for that product at that retailer since we started tracking it. It does not mean it is the lowest price the item has ever sold for anywhere.

Price history

Each product page shows a chart of every daily price we have recorded. History starts on the day we first saw the product, so newer listings have shorter charts.

Limits worth knowing

• Prices can change during the day. Always check the final price on the retailer's site before you buy.
• We only track retailers whose feeds we can access. A cheaper price may exist at a shop we don't cover yet.
• Delivery costs, discount codes and loyalty points are not included in our prices.

Affiliate links

Links to retailers are affiliate links. If you buy, the retailer may pay us a commission at no extra cost to you. This never affects which drops we publish or how they are ranked.
