If you do this, specify which quarter you're getting - one qtr has more steaks and the other has more stew meat, IIRC. $8.10/lb seems high compared to around here, but we're rural and dealing directly with the ranchers.
Also, depending on how jiggy you want to get in the kitchen, you can do TONS with that cow! You can request to keep all the fat, scraps, and bones. They'll usually separate them out for you. Make bone broth and home-can it (with a pressure canner) or freeze it - super healthy and taste is fabulous. I'm betting you can google how to make bone meal out of the bones, too, for gardening purposes. You can melt down the fat and make beef tallow for cooking, soap, maybe even candles - lots of uses. With the scraps that aren't suitable for ground meat or stew meat (like too stringy or whatever), you can often feed that raw to your cats or dogs. Gourmet and ultra-healthy pet food!
I buy meat in bulk and will never go back to buying at the grocery store. It makes my meal planning so much easier to know that I have beef, chicken, and lamb available in the freezer or home-canned for whatever recipes I'm considering. It makes my budgeting so much easier to do bulk purchases a few times a year versus being at the mercy of the grocery store sales (and grocery store quality!). I am really grossed out by how they run cattle feedlots and most large-scale chicken producing, and I really believe the health differences between animals that had happy lives grazing and hanging out in the fields or free-ranging, versus stuck in yuck-filled pens or cages go WAY beyond nutritional counts.
Also, if you don't want to devote that much freezer space to all that meat long-term, consider taking up home canning as a hobby. It saves you OODLES of money, tons of time, and you might find that you love it!!
Good luck with your decision!
