No, these aren't subscription boxes because you purchase each one on your own. Every box has its own theme and is crammed with products that cater or match that particular theme. As far as I know there are two kinds of boxes: the regular Althea box and the Trendy box. I'm not sure what the difference is, but I'm guessing the latter features newer or trending items.
I've been wanting an Althea box for months now, but they always get sold out in a matter of hours! Luckily, I was finally able to purchase one of their most recent ones just last week and it's their Althea Box #13: Vitamin Box.
I figured I was only able to score this one because it doesn't seem too in demand and is actually still available for purchase on the site. Either way I'm just happy I finally got my own box!
