a foot square--you can put into practice a unique system that will
appeal to the heart of every housewife. Publish that you will give a
free carpet of a certain size and grade when a fixed amount has been
traded. A square foot of a coupon represents a sum of money spent in the
store--perhaps one dollar. Every woman by measuring her room can learn
how many dollars’ worth of goods she must buy before she can have a free
carpet.
