Well, I'm not the OP and this almost sounds snarky, but after checking out your site (nice stuff, btw!) I just searched on FB and couldn't find anything for "fab apps bundle". have you considered marketing your product on Facebook? set up a Facebook Page. add a Like button to your homepage, or go all out with the little widget that links to said FB Page. Another possibility would be submitting your bundle for review by Mashable, SocialTimes, InsideFacebook, & other FB/social media blogs.
