In Spain, the purchase of food and basic necessities is becoming more and more complicated in the lives of some people. The constant increase in prices in supermarkets has led many consumers to look for ways to save on their family budget. That is why more and more people are choosing to compare prices in different establishments before making their purchases. What if we said that there is a price comparator ?
POY is a website that has become an essential tool for many consumers in Spain. It is a supermarket price comparator that allows us to find the products we need at the best price in different establishments, including some of the main supermarket chains such as Mercadona, Día, Alcampo or Carrefour .

With a simple and intuitive interface, POY provides updated information on product prices and offers on a weekly basis, making it easier to make purchasing decisions and helping you save money.
White brands only
As we said, POY updates the prices of eleven popular supermarket chains in Spain weekly , including Mercadona, Alcampo, Carrefour, Caprabo, Día, Eroski, Hipercor, AhorraMás, BonÀrea, Bonpreu and Consum. However, as a limitation, it must be taken into account that only white and cheap brand products are monitored.
In addition, it would be impossible to count the entire gender of each one, so some 55 basic products such as water, oil, pasta, salt, fruits, vegetables, eggs, milk and legumes are analyzed. Another thing to keep in mind is that the prices have been collected manually from a specific location, so the price may vary between cities .
Likewise, you will miss seeing comparisons of Lidl and Aldi, but they are absent because they do not have an online store and only have a weekly brochure. Also, some users claim the introduction of leading brands to know the real difference of the same brand in different establishments. This would help significantly to divide the purchase in different places and thus increase savings.

Indicators by colors
When looking at the table, its interpretation can be confusing. However, you only have to take into account the colors red and green . Prices are color-coded to indicate whether they are the lowest (green), the highest (red), or within an acceptable average (blue). This allows us to quickly see which is the best option to buy a specific product and which is the supermarket chain that offers the best prices in general at that moment. So in each product we can see highlighted the red with the most expensive price and the green with the lowest price of the same product.
In addition, on a weekly basis, the Poy website produces a graph in which it is compared which is the cheapest supermarket to make the purchase these days. In it we will be able to analyze if there has been a price increase compared to last week and how much is around the bag of food in each Spanish supermarket.
