Parents in Texas are about to spend way more on school supplies than the national average. In some parts, parents are going to spend just under $1000 vs the national average which is a little over $650. Its everything. Its supplies, and clothes, and electronics, and backpacks....with rising prices that doesn't help the situation either. This weekend in the state, Tax Free Weekend. You can save on sales tax for those items on your back to school list. August 5th through the 8th.
To help with your list and planning take a look at the items available from the state's comptroller.
