I actually just put my third order in at Thrive a few hours ago! I like it because of a variety of reasons.
1. Your first three orders, you get 20% off their prices (at least that was what was the case for me when I signed up).
2. Sometimes, if you place an order over a certain amount (maybe about $50 US dollars) you get something free, such as a jar of almond butter or something.
3. There are actually a ton of healthy foods there. I just bought some stuff to make home-made muesli, because I thought it would be cheaper. So, I bought medule dates, dried cranberries, etc. I also bought some chemical free and cruelty free cleaning sprays.
The downside is the $50 (I think) fee to sign up for the year. But, they have a thing where if you don't save that much or more, they will refund you the rest of it. Also, I think you can do a 30 day free trial.
I am a fan of Thrive, clearly. lol
