Is there any way I can reduce the amount and just face probation?

Third degree retail fraud carries up to 93 days in jail or up to 2 years probation, plus fines and court costs. The judge can also order counseling, community service, no drugs or alcohol, etc. The judge sets the bond, and you can make a motion to the judge to lower the bond, but if you have already posted bond the judge would likely leave the present bond in place. If you are found guilty or plead guilty, the judge decides on the sentence, which might or might not be probation. Try to get a plea under advisement, where if you complete the probation successfully, the case is dismissed. You need representation to help you through this.
