Costco is a mecca of all things holiday. From inflatable snowmen families to red wine by the case, if you need it for the holidays, Costco has it. But the discount mega store also has another very important item you should be buying for your holiday dinner: beef tenderloin.

It turns out, if you're in the market for a beef tenderloin for your Christmas dinner, Costco is the only place you should go. Their Kirkland Signature beef tenderloins come at two price points: $11.99/lb and $19.99/lb.

More Costco News:

The less expensive option nets you a a piece of U.S.D.A Choice beef that is between 5 and 9 pounds and untrimmed. That means you will still need to trim the meat of its fat and silver skin. If you'd rather an experienced butcher do that, you can pay $19.99/lb. This gets you a "peeled" beef tenderloin of USDA Choice (look for the word on the price marker).

To make certain of the big price savings, I also shopped three more national grocery stores. The price points:

Whole Foods

$19.99/lb for untrimmed beef tenderloin
$29.99/lb for trimmed beef tenderloin

Fresh Market

$15.99/lb for untrimmed "Premium Choice" beef tenderloin
$19.99/lb for untrimmed USDA Prime beef tenderloin

I did stop at a local grocery store, Publix, which is a common store throughout the southeast and east coast.* Their untrimmed beef tenderloin is available at $13.99/lb, but their butchers will trim the meat for you without extra charge. That's a sweet deal if you can find it.

So, what's the verdict?

Costco beats everyone's beef tenderloin prices.
