Nothing in the index as yet, but 250 pages in total spidered now.
I've just set it to post a new product 100 times over the next 24 hours (staggered cron in csv uploader), and now google is indexing a few pages every hour. Each time a post goes the sitemap is resubmitted, so seems its liking the attention now
So deep links, and more updates are working for me at the mo.
