Wayne, N.J. - Toys "R" Us is accepting used iPods this week in exchange for up to $100 in credit toward the purchase of new ones.

About 550 of the chain's 845 stores are participating in the trade-up program, which is the company's first for iPod.

Customers (over 18) will be issued trade-up cards for up to three pre-owned iPads in working condition. The promotion runs through Oct. 23 and is available in-store only.

 The trade-up program follows last year's launch of a trade-in program for video games, and the rollout of pre-owned titles last month.
