re: Why do some companies still mail out unsolicited thick paper catalogs?

Been in the direct mail business for 14 years. Magazines/catalogs generate business for advertisers. They wouldn’t do it if it didn’t work. Pays my employees & me, advertisers turn a profit, vendors get paid and keeps USPS in business. I know, frick a terribly run govt entity but some people rely on them.
It’s called commerce.
