Smarter Shopping
for Canadians
Perserving is a free price comparison tool dedicated to helping Canadians make smarter buying decisions by surfacing the true cost of what they buy — not just the sticker price.
Our Mission
Retail pricing is confusing by design. A larger package isn't always cheaper per unit. Sales aren't always sales. Comparing across stores is tedious.
We built Perserving to cut through the noise. We track prices across Canada's top supplements retailers and automatically calculate the cost per 100g — so you can compare every option side by side in seconds.
Our goal is simple: help you spend less on the things you buy regularly, without spending more time researching them.
How It Works
Behind the scenes and from your perspective
We track prices automatically
Our system monitors supplements products across top Canadian retailers — including major grocery chains, wholesale clubs, and specialty stores. Prices are collected regularly and stored with full history.
We normalize by unit
Every product is normalized to a standard comparison unit (100g). This means a 500g package and a 1kg package are directly comparable — you always see the true cost-per-unit, not just the package price.
You browse, compare, and save
Browse by category, compare all available options side-by-side, check price history to spot seasonal trends, and click through to buy directly from the retailer. No account needed.
