What most Marketplace monitors do
A typical monitor asks the customer to choose an item, keywords, price range, location and radius. It reruns that search on a schedule and sends an alert when a visible listing matches.
This solves a real problem: repetitive searching. Some products add price comparisons, duplicate filtering, resale estimates or profit tools. Those features help answer:
Does this listing look like a potential deal?
That is valuable information—but it is not the same as asking whether the opportunity is still fresh enough to pursue.
The three measurements
- Scan frequency measures how often the monitor checks.
- Listing age measures time since the seller created the listing.
- Delivery delay measures the time between detection and the buyer receiving the alert.
A fast score on one measurement does not prove a fast score on the others. A service may deliver within seconds after detection while the listing itself is older. A service may scan every minute but still be unable to detect a listing before Marketplace makes it visible.
What the main products publicly emphasise

Where Deal Shark is different
Deal Shark is not positioned as another exact watchlist tool. It provides a shared Sydney reseller-discovery feed during defined weekend sessions.
- It verifies the listing’s creation time.
- It excludes listings aged 15 minutes or more.
- It displays the created time and alert time.
- It sends the price and original link directly to Telegram.
- It can surface opportunities outside the keywords a buyer would have predicted.
The simplest comparison
Other tools help identify what may be underpriced. Deal Shark helps you reach a fresh opportunity while there may still be time to act.
Which approach should you choose?
Choose an exact watchlist when you know the specific model, maximum price and location you want, and you value configuration or price-analysis tools.
Choose Deal Shark when you want a ready-to-use Sydney discovery signal, a fixed creation-age threshold and Telegram delivery without constructing multiple watchlists.
The two approaches can complement each other. The honest question is not “which product has the smallest advertised interval?” It is “which measurement and workflow helps me act on the opportunities I care about?”
Freshness still is not a guarantee
A listing under 15 minutes old can still be pending, sold, removed or claimed by another buyer. Sellers also choose whom they answer based on price, tone, pickup timing and convenience.
Freshness improves the information available to you. It does not guarantee the seller’s decision.
