Here’s a simple 70 cent solution to keeping your kiddoes happy at Target– there’s a cooler of juices (including 100% fruit juice boxes) off of the Target café area! And the juice boxes are only 70 cents. You will also find individually wrapped real cheese sticks and little snack packs of apples, etc. It is a mystery to me why you don’t see families in line at the café to purchase these items. Why go to the Target Starbucks for overpriced juice and comparably unhealthy snacks when you can save at the cooler next to the Target café. 
Now your little ones have something to occupy their time long enough for you to get some of your shopping done. And you’ve saved money while providing a wholesome snack for your kids!
