The point they were making is: look, it's so cheap it's the cost of one sandwich.

Does that point still stand if it's not the cost of one sandwich, unless you're paying a fortune for a sandwich?

The cost of a sandwich ranges beyond $0.50 to $200.00. It depends on the sandwich adds about as much to the conversation as "it costs less than a sandwich".

And to be clear by "beyond" I mean some sandwiches cost less than $0.50, and some sandwiches cost more than $200.00
