eSeller Street launched what it says is the first pay-per-search market research tool targeted to eBay sellers. It offers 90 days of eBay research for all US categories, excluding Motors and Real Estate. eSeller Street recommends sellers use the tool when researching prices and keywords, making inventory purchasing decisions and to better understand competitors.

Founder Michelle Waldorf said, "the addicting aspect of the site is seller research. Users typically research 5-10 sellers at a time every week or so."

The service offers 20 searches for $7, and offers two free credits upon sign up.
