Just started a business www.pleasereturn.me which sells recovery labels for devices. Going well so far, we have roughly a 75% return rate but we want to grow our user base (Who doesn't?).<p>I am curious to where you advertise online, if there are any niche services that have worked out well for you, or if you can recommend something for our service.<p>Another nagging question I've had, how is advertising on Facebook compared to Google? Better or worse?<p>Thanks HN
