Target Corp. is offering consumers prepaid Target gift cards in exchange for used electronics, as part of a campaign to encourage recycling.

The service, which launched Aug. 24, is available in Northern California stores that feature Target Mobile centers. Target's Electronics Trade-In program will roll out to additional stores in September and will be available at approximately 850 stores by yearend, a company spokeswoman said.

The program "encourages guests to be eco-friendly and get rewarded for it," she said.

Consumers may trade in a variety of electronics, including new or used Apple Inc. iPhones and iPods and other cell phones, DVD players and video games.

Consumers can receive gift cards valued at up to more than $200 per donated item, depending on the product and its condition.
