BasketWatch

BasketWatch tracks the prices of more than 50,000 products at Ireland's four biggest supermarkets, Aldi, Tesco, SuperValu and Dunnes Stores. Prices are collected every night, with history back to May 2026, and the same product is matched across the four stores.

Ask in plain English, for example:

• Where is this product cheapest right now?
• Here is my receipt or shopping list: what would it cost at each store, and which cheaper own-label swaps are there?
• What would the same basket have cost on an earlier date?
• Which biscuits have no palm oil? Which cereal has the least sugar? (from each retailer's own ingredient and nutrition data)
• Which drinks prices really rose since July, and which were just offers ending?
• What is on promotion at Tesco, including Clubcard prices?
• What is new, what has been delisted, and how has a product's price moved over time?

Every answer carries the retailer, the price, the date and a link to the product. Regular shelf prices, promotions and loyalty prices are kept separate, so an offer ending is never mistaken for a price rise.

Checking where a product is cheapest is free, with no account. The other tools need a BasketWatch account: you sign in with your email and a 6-digit code, with no key to copy. Accounts use prepaid credits, one credit per record returned. Every tool only reads data: nothing can be bought, booked or changed.

Prices are those shown on each retailer's website when collected; in-store prices can differ. Ingredients and nutrition are for information only: always check the pack.
