Just created a new product page and submitted url via GWT. Went to google.co.uk within a few seconds and it had been crawled, indexed and ranks on page 1 for the main keyword (incognito mode in Chrome). The other 9 results come from just 4 domains, all mom & pop type companies (although the product isn't currently available through brands like ebay and amazon).
We're a relatively small site and G. normally takes days (if not weeks) to crawl and index new pages. Hopefully, this will last (page has no backlinks and 1 internal link, yet...) and is not an "artificial high" for new content.
