Kids outgrow their bikes almost as fast as they outgrow their clothes it seems. So it's a good thing that Toys 'R' Us has a solution to this problem.

Bring the old one in to see $10 off any bike or trike regularly priced $59.97 or less, $20 off those priced $59.99 - $99.97, $30 off those $99.99 - $149.97, and $50 off those priced $149.99 or more.
