Exclusively for Prime members, Amazon offers the Luxury Sun Care Sample Box bundled with a $19.99 Amazon Credit for $19.99 with free shipping. (The credit must be used towards purchases of similar luxury sun care products.) Assuming you'll use the credit, that's tied with our March mention and makes the sample box essentially free. Each box includes eight or more items, with products such as body butter, lotion, lip balm, and perfume. It's limited to one box per customer.

Note: This item ships in five to seven days.
