I have purchased a few with Groupons. These monthly subscriptions can be a little bit pricey after shipping, but the deal sites are a perfect way to try them out.
My personal favorite is Klutch Club (www.klutchclub.com), which specializes in healthy foods. I feel like I got those most products that I would actually use, and I really got my money's worth. I'm actually considering signing up for a bonafide monthly membership! If you want to try out this company (I swear I am not being paid!), buy the "Best-of box" with non auto-renewing, and use code FREECLUTCH - you'll have to pay shipping, but you'll get one box for free!!
Let me know how you like it! OH! Here is a picture of all of the stuff I got in my Klutch box:
Peace. Love. Serene.
