Exclusively for Prime members, Amazon offers the Women's Daily Beauty Sample Box bundled with an $7.99 Amazon Credit for $7.99 with free shipping. (The credit must be used towards purchases of similar beauty products.) Assuming you'll use the credit, that ties last week's mention and makes the sample box essentially free. Each box includes 10 or more beauty items. It's limited to one box per customer.

Note: This item ships in one to two weeks.
