Alert ready — your threshold is met
A simple journey

Three steps, then the radar gets to work.

Each step answers a specific decision. You know what is monitored, at what price and how you will be notified.

01

Find the right card

Browse Pokémon, One Piece and Disney Lorcana. Confirm the name, set, number and finish before adding it.

Outcome · The right card, without ambiguity
02

Choose your version

Select a version that can be monitored. Current coverage targets raw or graded English cards (PSA, BGS, CGC, SGC, TAG, ACE); a monitoring request may be required.

Outcome · Monitoring matched to the card you want
03

Set your threshold

Enter your maximum price in CAD or the discount you want below market value. Enable Discord and validate the test message.

Outcome · Useful alerts based on your rules
Two ways to define a good deal

A clear threshold for the way you buy.

Choose an absolute budget or let Grailwatch compare the listing with the available market value.

Exact budget250 $

Maximum price

Get an alert when the known delivered price is equal to or below your chosen amount.

Example · Alert me at CAD 250 or less, including shipping.
Market discount−12 %

Below market

Get an alert when the listing is far enough below the card’s usable market value.

Example · Alert me when the price reaches 12% below market.
What happens next

From the listing to your Discord message.

Monitoring follows a clear sequence. If essential data is missing, the alert waits instead of sending you a false signal.

01A listing is observed

Grailwatch records the source, seller and available price.

02The final cost is checked

Delivered price is used when shipping costs are known.

03Your rule is applied

The amount is compared with your ceiling or discount below market.

04You are notified

An eligible deal can trigger a message based on your access and preferences.

Clear boundaries

A signal to help you decide, never an automatic purchase.

Grailwatch compares listings from the sources available for each card, including eBay Canada. The source stays visible on every deal.

Grailwatch never buys or bids on your behalf.
A below-market alert requires a usable market value.
A delivered-price alert requires known shipping costs.
Always check the card, seller and total on the marketplace.
