For Prime members only, Amazon offers an Aveeno Sample Box bundled with a $7.99 Amazon Credit for $7.99 with free shipping. (The credit must be used towards purchases of similar Aveeno items.) Assuming you'll use the credit, that's tied with last week's mention and makes the sample box essentially free. Each box includes six or more items, and this deal is limited to one box per customer.

Note: It's expected to ship in one to two weeks.
