I highly recommend taking advantage of using the MySchoolBucks payment software (yes, there's an app!).  Here you will have the opportunity to view your child's purchases daily as well as have more control over how money is to be spent by using the set limit features.  You can also have low balance alerts sent to your email, set up auto pay, and make one time payments using your phone or tablet.  There is a small fee for payments but the account to view your purchases is completely free.
