Exclusively for Prime members, Amazon offers a Men's Luxury Grooming Sample Box bundled with a $19.99 Amazon Credit for $19.99 with free shipping. (The credit must be used toward purchases of similar men's grooming products.) Assuming you'll use the credit, that ties last week's mention and essentially makes the box free. It includes samples from brands such as Proraso, Toppik, Baxter, and Vaughn. It's limited to one box per customer.

Note: It is estimated to ship in 1 to 2 weeks.
