It's not always easy to become an affiliate so it may take time to get a good rooster of stores. A common approach is to crawl the data even if you don't have an affiliate deal. Not only is it proactive but it also enhances the product since it will show more alternatives.

Yep. We started with scraping, though we prefer affiliate data feeds. We still use scraped data while we wait for the affiliate approval.
