Interactive mobile tech firm PlasMedia Mobile has come out with Coupon Envy, a Web-based solution that opens the world of mobile marketing to small and mid-sized local businesses.

PlasMedia offers rates as low as $17 a week for 2,500 messages. The service includes response rates and other reporting and is being marketed as an ecologically friendly way to advertise.

"Mobile marketing is not just for the big guys anymore," said Dean Talley, CEO of PlasMedia Mobile parent PlasMedia Productions. "Mobile couponing is a way for small and midsize business owners to reward their best customers. They can provide special offers, discounts, event invites, news, or anything else their customers might find valuable. In return, the business owner gets the holy grail of marketing: their target consumer's undivided attention in a database they can remarket to."
