Was going to agree with above. Chances are some of these things being stuck together are being called higher grade meat when it could be from other parts and doesn't have same quality and taste, etc.
Think of it this way, let's say one cut right now is $12/lb, now would you be happy paying that if you knew that cut was made from a package of "beef for stew" @ 1.20/lb glued together? I'm not because you are getting a substitute. Regardless of similar taste. I'd rather just do it myself with the $1.20 meat if it was that simple to do.
Or better yet, I've always enjoyed my skillet steaks and other cheap cuts when cooked right. (Usually just faster. I'll admit it's no nice just thick hank of steak, but neither is it any worse I think than any of these real expensive tiny cuts like the fillet mignon.)
