Minneapolis - Target has expanded its CE trade-in service to 1,490 stores, and is accepting additional categories.

The service, provided in partnership with Boston-based CE exchange and recycling service NextWorth, will now be offered in all stores with Target Mobile centers.

The trade-in program now also accepts pre-owned calculators and DVDs, in addition to iPods, iPads, iPhones, cellphones, Nintendo DS units and video games.

"The expansion of Target's Electronics Trade-in service comes at a time when parents are really looking to save on back-to-school purchases," said Target merchandising VP Nik Nayar. "Our service is budget-friendly and it gets Target's guests involved with reducing e-waste."

Products are evaluated on-site, and values are determined based on the model and condition of the item. Customers then receive a prepaid card for the value of the trade to put toward their next Target purchase. Items can also be exchanged online at www.NextWorth.com, where customers have the choice of cash or a gift card for their trade-in.
