We have collected data on wine prices from the producer and compared it with the prices at which these wines are sold in other countries / regions / stores. This allowed us to find out the places where the wine is most expensive, as well as to understand which sellers are overpricing.
The idea is simple. The closer the coefficient is to 1, the more fair the price is. With the help of coefficients, you can compare prices in different stores. For example, if a store sells your favourite wine at a coefficient of 1.2 and another 1.6, the first store is more honest with its customers.
At the moment, we are collecting more and more data on wine prices in different countries. We hope that our project will allow you to buy your favorite wines at the most attractive prices.
