School time is just about here. That means there are purchases to be made for back to school. Check out 2012 Sales Tax Holiday listing to see if, and when, your state is offering a sales tax holiday. Shopping during a sales tax holiday can save you money, because you do not have to pay sales taxes on items covered by the holiday. A back to school sales tax holiday generally covers clothing, shoes, and sometimes other items that your child(ren) will need for school, but it varies from state to state.
