Frequently asked questions about Cartouche prices
When are Cartouche products cheapest?
Real drops cluster around Black Friday, the sales and the launch of a new model, which pushes the previous one down. The score on each Cartouche page tells whether today’s price is already a low point compared with the usual price.
How do I know if a Cartouche discount is real?
DeaLynx compares today’s price with the product’s six-month usual price, never with the retailer’s strike-through price. A discount only counts when today’s price is genuinely below.
How can I be alerted to a drop on a Cartouche product?
Open the product page and track it: the price is recorded daily and an alert warns you as soon as it falls below your threshold or its usual price.
