Everything you need to know about using Price Tracker Ireland.
TrolleySpy is a community-driven grocery price comparison tool for Irish shoppers. Our team maintains a verified database of prices across Tesco, Lidl, Aldi, Dunnes Stores and SuperValu. You can also log your own prices as you shop.
The Add Price form lets you record what you paid for a product. It works as a cascade — each step unlocks the next.
Defaults to today. If you're logging a price from yesterday's shop, change this first — it affects which price auto-fills from the database.
Only categories with products in our database are shown. The number in brackets tells you how many products we have in each category. If a category is missing, we haven't added any products there yet — use the Suggestions page to let us know.
Products load after you pick a category. If the product you want isn't listed, it's not in our database yet — please suggest it and we'll add it.
Brands are linked to products in our database. For shop own-brands (e.g. Tesco Finest, Milbona, Cowbelle), selecting the brand will automatically lock the shop — because those brands are only sold in one shop.
For most brands you pick the shop yourself. For shop own-brands the shop is auto-selected and locked — you can't change it because that brand is only sold in one place.
Auto-fills from our database when a product and shop are selected. If we have a price on record, it appears automatically. You can change it if the shelf price is different — that's how we keep the database up to date through community contributions.
If our database shows an active promotion for this product in this shop, the checkbox pre-ticks automatically and shows the deal details. Untick it if you paid full price — for example if the promotion ended but our records haven't updated yet.
Some products like salmon or deli cheese are sold by weight — priced per kg but you buy a specific amount. For these products the price field shows "Price per kg" and a "Weight purchased (grams)" field appears below. Enter the weight on the label and the total cost calculates automatically.
The Compare Prices page searches our verified price database. Type any product name — even just one word like "butter" or "milk" — and see all matching products with their current price across every shop.
When the same product appears in multiple shops, the cheapest verified DB price gets a "✓ cheapest" label. Results are sorted cheapest first within each product group.
Each result shows the brand name so you can tell the difference between, for example, Avonmore milk and Tesco Own Brand milk — both under "Milk 1L" but with different prices.
If an active promotion is running for a product in a shop, the deal description and savings percentage show on the result. For the full list of current deals, see the Deals & Promotions page.
Each result has a "+ List" button. Free users can add items to one shopping list. Tap the button — if you're not logged in, you'll be taken to the free registration page and brought straight back with your item saved.
The Deals & Promotions page shows all active sales and multibuy offers across all five shops. No login required — bookmark it and check every week.
We update promotions manually when the weekly leaflets come out — typically Wednesday/Thursday for Lidl and Aldi, and throughout the week for Tesco, Dunnes and SuperValu. Each promotion shows its end date so you know how long the deal lasts.
Promotions ending within 3 days show an orange or red badge. "Ends today" means the deal expires at midnight.
Build your weekly shopping list and see estimated prices before you go to the shop.
You can create multiple named lists — for example "Weekly shop", "BBQ weekend", "Pharmacy". Switch between them using the tabs at the top.
Select a category, then a product, then a shop, then a quantity. Prices load from our database automatically — you don't need to enter them manually.
Price notes are a quick personal scratchpad — write down any price you see, for any product or shop, even ones not in our database.
Select "Other" from the shop dropdown and a free text field appears — type any shop name you like.
The Suggestions page is how you help us build the database. We review every suggestion and add valid ones ourselves — your suggestions never go directly into the database, they go into a queue that our team reviews.
You can attach a photo to any suggestion — shelf label, receipt, product packaging, or shop front. This helps us get the details exactly right. Photos are stored securely and only visible to our team.
Your previous suggestions appear below the form with a status: Pending (under review), Approved (added to the database), or Rejected (duplicate or out of scope).
Use the Forgot Password link on the login page. Enter your email and we'll send you a reset link valid for 1 hour. Check your spam folder if it doesn't arrive.
You can download all your price entries as a CSV file from the Export CSV page. This includes product name, shop, price, weight (for weight products), total cost, and date.
