My son's pretty set for school clothes.
I'm going over his school supply list to see what we already have and what else we need.
Since I'm off work tomorrow (and it starts on Fri in Va), I'll hit the store first thing in the morning when it opens and get it over with.
It varies by state.
For Virginia:
August 5-7, 2011: School Supplies and Clothing.
"During this three-day period, purchases of certain school supplies, clothing and footwear will be exempt from the Virginia sales tax. Each eligible school supply item must be priced at $20 or less, and each eligible article of clothing and footwear must be priced at $100 or less."
