For Prime members only, Amazon continues to offer a Mr. Olympia Sample Box bundled with a $9.99 Amazon Credit for $9.99 with free shipping. (The credit must be used towards select sports nutrition purchases.) That's tied with our May mention of a similar box, and assuming you'll use the credit, it's essentially like getting these items for free. Each box includes ten or more samples. A limit of one credit per account applies.

Note: It's expected to ship in one to two weeks.
