Not Butcher Box, but we've been enjoying some awesome meat from Hometown Meats in Luling, TX. Pretty sure they ship in US. We like them because their meat is fantastic, they are "local" to us, only about an hr away. And they are part of Texas Slim's Beef Initiative. Same folks as K&C Cattle Co. Pretty sure they accept btc too.

It's not local to me, but I still might buy from the Beef Initiative until I find something more local.
