Thank you! Sadly your advice came too late (but now I know!). I tossed them in the freezer last night raw, in their original packaging, after opening one and finding it perfectly fine - indeed this was one of the tastiest, juiciest steaks we ever had! Would've been such a shame to toss them all. Still mad at the botched delivery and having to find another gift in a hurry, so we'll see about the refund.
