Is there a website for all of the discount supermarket chains

There isn't a single comprehensive website that lists all discount supermarket chains globally, as the availability and popularity of discount supermarkets can vary greatly by country and region. However, you can find information about discount supermarket chains through various resources:

**Consumer Reports** - They often review supermarkets and can provide insights into discount chains.
**Supermarket News** - This website covers industry news and often highlights different chains, including discount ones.
**Local Websites** - Many countries have local consumer websites or blogs that discuss grocery shopping and may have lists of discount supermarkets.
**Wikipedia** - The page on supermarkets often includes a list of various supermarket chains, including discount stores.
**Regional Grocery Apps** - Some grocery shopping apps or websites might categorize supermarkets, including discount options.
