How BoozDealz Works
We find the deals. You decide if they're worth it.
BoozDealz is designed to make alcohol shopping simpler by bringing together retailer prices, product information and price history in one place.
1. We collect price information
We collect product, price and availability information from participating retailers and affiliate programmes. The retailers and data sources we track may change over time.
That means BoozDealz does not claim to represent every retailer or every price available in the UK.
2. We match products carefully
Before comparing prices, we need to make sure we are comparing the same product. Where reliable identifiers such as EANs are available, they can help us match products across retailers.
Where there is uncertainty, we do not want to automatically assume that two listings are the same product.
3. We look beyond the advertised discount
A retailer might say that a product is 30% off. That does not automatically mean it is a great deal.
Where enough data is available, BoozDealz looks at historical prices, prices from other tracked retailers, availability and other signals before assessing the opportunity.
The important bit
We are interested in whether the price is genuinely attractive, not simply whether a retailer has put a discount label next to it.
4. We calculate a Deal Score
Our Deal Score combines five factors to produce a score out of 100: historical price advantage (45 points), approved competitor comparisons (25 points), recent verified price reductions (15 points), historical price rarity (5 points) and availability (10 points). Points increase smoothly with stronger evidence rather than being awarded in fixed discount bands. Recent reduction points expire after seven days; competitor comparisons require approved matches. Confidence is assessed separately and describes how strong the supporting evidence is.
You can see the full methodology behind the score on ourDeal Score methodology page.
5. We show Confidence as well
A high Deal Score is useful, but it is also important to understand how strong the evidence behind it is.
That is why BoozDealz shows a separate Confidence level. It reflects how strong and reliable the supporting evidence is, including factors such as price-history length, observations, retailer coverage, data consistency, product matching and current price verification. Repeated observations of an unchanged price can strengthen the history, while missing observation days or a shorter tracking period can limit Confidence. A strong Deal Score and strong Confidence are related but they are not the same thing.
High
Strong supporting evidence.
Good
Useful evidence with some limitations.
Limited
Weaker evidence or shorter history.
6. You make the decision
BoozDealz is here to give you useful information so you can decide whether a price is worth considering.
We will not tell you what you should buy, and we will not pretend that we know more than the evidence allows us to know.
We find the deals. You decide if they're worth it.
One important limitation
BoozDealz can only compare the retailers and data sources that we actually track. Prices can also change, products can sell out and retailer information can become outdated.
We therefore aim to be transparent about what we know, what we have checked and where there are limitations.
