You can get a deal through Groupon that will give your kids some time at a local Bounce U facility for a fraction of the normal price.
Choose from the following locations: Blackwood, New Jersey, Cherry Hill, New Jersey, Exton, or Oaks, then choose between the following options:
For $20, you get 5 open-bounce passes (up to a $40 value).
For $35, you get 10 open-bounce passes (up to an $80 value).
Be sure to read the fine print on the deal, and you'll need a Groupon account if you don't have one already.
