There are several new Sample boxes available for Prime Members right now.  One of my favorites is this Children’s Sample Box.  It costs $4.99 but you’ll get a $4.99 credit to use on snacks later!  Please note these may sell out.  Price and availability was accurate at time of listing.

• For a limited time, buy this box for $4.99 and receive a credit of $4.99 towards your next purchase of select children’s snack foods shipped and sold from Amazon.com. See Terms and Conditions below for details.
• A week after your product ships, you will receive an email with instructions on how to use your promotional credit.
• Limit one promotional credit per customer. Sample box is available for Prime members only. Offer available for a limited time. Items may vary based on availability.
• Each box contains 10 or more samples from various brands.
