Back-to-school shopping can feel like a race to buy everything before the first bell, but rushing may cost families more than necessary. In 2026, families with K-12 students expect to spend an average of $863.86 on school-related purchases, according to the National Retail Federation. Nearly half of shoppers who had not finished buying their supplies in early July said they were waiting for better deals. That makes patience a practical strategy for finding back-to-school savings, especially on items students do not need immediately. If your child can get through the first few weeks with the essentials, these seven purchases may be worth postponing.
