Magnet Cards have an 80% higher coupon redemtion rate than other regular mailed  postcards! Our patented magnet cards are 100% approved by the USPS for stand alone mailing as the polarity doesn't interfer with postal processing equipment; plus the size of the magnet wafer doesn't add weight that can effect postage rates.  Our cards can be blown-in our magazines as inserts and used in both our DAL and wrap programs.
