Newbie here so take it easy on me. On a spontaneous splurge I bought a 8lb rib roast from Costco online that was advertised as Australian wagyu with a mailing grade of 8+. (please leave comments out regarding how dumb this purchase may be). Ok, so I got my beef today, and I'm a bit skeptical that I got what I paid for. The package came from a company in New Jersey called "D'Artagnan". The rib roast is stamped "AUSTRALIA INSPECTED". I went to D'Artagnan's website and they sell quite a few different products, including several beef selections in their "gourmet meat" section. They sell a 9-10 lb rib roast that is Australian grass fed beef imported from Australia. They make no claims that it is wagyu or anything, and this roast sells for $128.99. They also have a "Kobe-style" rib roast that they sell that is a 16lb roast for $479.99, that they say is raised in Texas. Nowhere on their site does it say that they sell Australian wagyu. I got the roast and I am afraid that they shipped me a $128.99 piece of Australian grass fed beef for $300. Is there any way I can tell if I got duped? Is this meat supposed to be stamped "wagyu" or anything? The meat looks nicely marbled but I have never purchased or eaten wagyu so I don't really know what I am looking for. I emailed Costco and am waiting to hear back from them. Any advice would be much appreciated!
