The POPSUGAR Must Have box is always a really good value, because for $40, you are guaranteed to get at least twice that and usually much more. It's also unlikely you won't get at least a few things you really like. I will admit that their customer service is sorely lacking, but the box has been good enough to compensate thus far.
Each month, you receive a series of items, generally at least one for beauty, wellness/fitness, home, food, and fashion. The items are always top quality as well. They also do a good job securing the items and packing the box so everything is presented nicely and safe from being tossed around a delivery truck.
