For Prime members only, Amazon offers a range of product samples with a $2 Amazon Credit for $2 each with free shipping. Assuming you'll spend the credit, that's tied with our February mention and essentially makes these samples free. Save on snacks, vitamins, beauty items, and more.

Note: The credit is only good when purchasing full-size items from the product sampled. It's also limited to one credit per sample per customer.
