As kids get older the back to school supply list gets longer. My 3rd grader has 13 items on her list. On my 6th graders supply list there are 36 items – YES – 36 items! Â Now the countdown is on to actually buy the supplies. Do you shop around and compare prices at different retailers or do you just order online? I cannot imagine the cost if you have 3 or more kids and have several supply lists! Life was easier when they were in preschool!
