Pokémon Center
The source catalog: products, prices, stock, and product details.
New informationThe path
Four simple handoffs.
The complicated bits stay behind the scenes. The visible job is a clean path from store to signal.
2
ZenRows
Handles the store’s security checks so the watcher can read the catalog.
Safe access3
Private watcher
Checks, compares the latest view with the last known view, and records changes.
Finds the signal4
Database + email
The history is saved, and Luna sends a focused alert to Ray and friends.
Useful alertThe rhythm
Three views. One complete picture.
The watcher rotates through the catalog so each cycle has a different lens on what is happening.
ANY CHANGE → ALL THREE
01
Newest
What just arrived or was recently added.
02
Top Selling
What other collectors are reaching for now.
03
Price High to Low
The highest-value cards and products first.
Instant rule: when any view changes, the other two are pulled right away to make sure nothing important is missed.
The catalog memory
Every product gets a useful little record.
That makes a price move, a new listing, or a restock easy to recognize instead of making someone scan the whole store by hand.

The moment that matters
A small, readable alert.
Only a change earns attention. The email keeps the product rows compact, uses Eastern Time, and gives each item a direct path back to the catalog.

The pace
What it costs to keep looking.
