Snipe the listing before anyone else sees it.

Underpriced collectibles disappear in minutes. eBay's own saved-search email shows up the next morning. Netletz re-checks your search (eBay every 2 hours, other sites as often as hourly), layers your own price and exclude-word rules on top, and alerts you on the next check after a match appears.

eBay is best effort: it sometimes blocks automated reads, so some checks are skipped and retried.

How it works

Paste a search. Layer your rules. Done.

1

Build the search

On eBay (or Mercari, Etsy, Grailed, StockX, etc.), set every filter you can — keywords, category, condition, location — and sort by Newly Listed. Copy the URL.

2

Layer your rules

Title must-include, words to exclude (parts, broken, copy), max price, required condition. Add plain-English extras like 'US sellers only' or '99%+ feedback'.

3

Snipe the drop

An alert on the next check after a real new listing matches — with title, price, condition, and a direct link.
