The guides
Free guides for shopping construction materials in Quebec
While we’re building the tool, we’re publishing what we learn about prices, hardware stores and flyers in Quebec. Updated monthly. (In French for now.)
FAQ
Frequently asked questions about construction material prices
Is comparing construction material prices really free?
Yes. Pasting your list and seeing the savings estimate is entirely free. You only pay when you want to reveal the actual store names or unlock Pro features. Full pricing details ship when the beta opens. The first 125 signups on the waitlist lock in 50% off for life on every plan.
Where do the material prices come from?
Public weekly flyers from Quebec hardware stores, official retailer catalogs and Google Shopping. No scraping, nothing unlawful. The same public data that Flipp and Reebee rely on, applied to your construction materials list.
How accurate are the compared material prices?
We cover 80 to 90% of popular construction and renovation SKUs in Quebec. For the remaining items, we mark them "verify in store". We prefer acknowledging uncertainty over displaying an estimated price.
When will Bâtir à Rabais be available in Quebec?
Private beta in May 2026, open to waitlist subscribers. Public Quebec launch in June 2026. Sign up to be notified first.
I’m a materials retailer: how can I receive qualified leads?

Your receipts see what our AI can’t.
Our AI compares the prices listed on hardware-store websites. Your receipts hold the real prices paid in-store: member prices, contractor rates, in-store flash deals, regional variance. Share them, earn free comparisons in return.
You snap a photo
A photo of your receipt after shopping. RONA, Canac, Home Depot, Patrick Morin, BMR — any chain. No typing required.
AI reads every line
Logo detection, total cross-validated against line items, unique receipt hash. Under 5 seconds, no copy-paste possible.
You earn comparisons
+1 free comparison per validated line. Monthly cap matches your plan’s quota (3 on Free, up to 500 on Entrepreneur).
What your comparisons see that others don’t.
Member & contractor prices
RONA Pro, Home Depot ProXtra, Canac discounts. Invisible publicly, visible on your receipts.
Regional variance
A 2x4 in Sainte-Julienne doesn’t cost the same as in Sept-Îles or Montreal. Your receipts prove it.
Off-flyer SKUs
The vast majority of catalogues never make it to a flyer. Receipts capture the real day-to-day prices.
In-store flash deals
Same-day in-store discounts, never on the website. Your receipt records them.
