For Prime members only, Amazon still offers this Snack Sample Box bundled with a $9.99 Amazon Snacks Credit for $9.99 with free shipping. (You'll receive an email a week after shipping with instructions on how to use your promotional credit.) If you'll use the credit, that's $10 off list and essentially a box of free samples. It includes a variety of nuts, chips, bars, and protein packs.

Note: It's not expected to ship for 5 to 7 days.
