So I ask those with experience shopping at US Wellness Meats, what are the best products/deals in your opinion?
Chuck roasts. They contain a lot of fat and are tasty. You can cook them like roasts or cut them into thick slices while they are semi-frozen and cook them like steaks. They are as cheap as any form of solid beef sold by US Wellness.
Their beef liver is good and is one of the cheaper items.
If you want lean beef, their flank steak and eye of round roasts are very lean.
What in particular should be avoided?
I wouldn't necessarily avoid their pemmican, but you should be warned that unlike real pemmican, the US Wellness product needs to be refrigerated. It seems to contain water. Real pemmican is dry.
Similarly, their beef suet isn't really suet. It's miscellaneous bits of soft fat with a huge amount of connective tissue mixed in. I usually render it by simmering in a large amount of water. The temperature has to be kept low, otherwise the connective tissue develops an unpleasant taste. The fat floats to the top and the connective tissue makes a nice gelatinous broth. Strain the hot broth to remove the connective tissue. After refigeration, the fat can be lifted off in a beautiful solid white disk. If you keep the rendering temperature low, the connective tissue doesn't taste bad and you could probably use it for something, although I usually throw it away.
Their lamb is good (I particularly recommend the lamb hearts) but it's not vacuum packed. It's hand-wrapped in many layers of thin plastic wrap. Their beef is vacuum packed in heavy plastic.
Personally, I avoid chopped meat because I find that it doesn't taste as good as solid chunks of meat (i.e. roasts). Also, roast are sterile inside, and occasionally I like to eat my meat raw. This is much safer with roasts than with prepackaged chopped meat.
But if you buy chopped meat from US Wellness, I recommend the Northstar bison (sold by US Wellness) instead of their own chopped beef. I've tried both several times and found that the bison tastes better.
You didn't ask about their customer service, but for completeness, here are a few comments.
In general, I'd say it's excellent. However there is one quirk. They say (or used to say, I haven't checked recently) on their site that orders received before 10 am will ship that day. This isn't alway true. Pretty often, an order received before 10 am one day won't ship until the next day. In order to be sure that they ship by Wednesday (their last shipping day of the week), I've gotten into the habit of ordering before Tuesday.
I've ordered about three thousand dollars worth of meat from them over the last couple of years, and there have only been two tiny problems. They once sent two beef tongues with torn vacuum packaging. Air had gotten into the packages and frost had accumulated on the meat. I called to complain and a very nice woman instantly gave me credit for the full amount of the purchase.
The other problem was that once they sent me the wrong items -- some kind of pork roasts instead of some kind of beef roasts. The person who packed the box must have misread the slip. I didn't bother calling them about that.
In general their packing is done very well.
