I have to admit I'm not a big fan of Walmart, but I did want to try the quarterly beauty box. These are free boxes of samples from major companies typically sold at Walmart - you simply pay $5 per box for shipping (so $20 a year).
There was nothing exciting about this box, since most of these things are products you can buy at, well, Walmart. However, if you're debating about picking up some of these brands of items, the box gives you a chance to try them first.
