Free shipping with Prime or with orders $25 or more.
This is free to stream on Amazon Prime, but the blu-ray contains a wealth of extras, including two commentary tracks.

This particular listing looks to be just a re-issue of the original release.
Walmart also has it for $5.09 but free shipping is only available on orders of $35 or more. Store pickup is not an option.
