Get a full-day pass to Magic Waters Waterpark for only $11 (reg. $24).   Doesn’t show a limit to the passes you can buy.

Or how about a half-bushel of local and organic produce with home delivery for only $20 (reg. $40) from Delivery Produce Co.   This is a full week’s worth of fresh fruit and vegetables.  Looks like their delivery area is a crazy rectangle with a border along the lakefront – north to North Chicago and west to Oak Park and south to I-94.  They have a box where you enter your zip to see if you qualify.
