I would venture a guess that the ad read what it did because those who submitted the ad, themselves, didn't know the difference between the meats. Thanks for the answers, regarding the butchers, and I also have heard that the butchers at Big Star Grocery on Cloverdale rd are some of the best in the area.
As for meat I've actually found some fairly good meat at Sam's Club but most is in bulk so you have to buy so much and it's usually more than I need but it's pretty good quality. Publix also has some good selections and you can ask their meat department employees to cut you what you want but I don't know if they are technically butchers or not.
