Walmart offers its seasonal Walmart Beauty Box for free plus $5 for shipping. That's tied with April's mention and the lowest total price we've seen thus far. Each box contains multiple seasonal free samples. Contents may vary from box to box, but may include samples from brands like Olay, Secret, and L'oreal.
Note: Be sure to cancel your subscription after your box has shipped or you will be charged for and receive additional beauty boxes each season.
