For Prime members only, Amazon offers a K-Cup Coffee Sample Box bundled with a $7.99 Amazon Credit for $7.99 with free shipping. (The credit must be used towards purchases of similar coffee products.) Assuming you'll use the credit, that makes the sample box essentially free. It's also tied with our August mention as the best such offer we've seen from Amazon this year.

Each box contains seven or more samples from brands including Peet's Coffee, Caribou Coffee, Newman's Own, The Original Donut Shop, Brooklyn Bean Roastery, and Green Mountain Coffee.

Note: This item usually ships within one to two weeks.
