Gwen Falkowski and her family took full advantage of last weekend’s sales tax holiday in Georgia. “We’re out because it’s a tax-free day and we wanted to get some [school] uniforms, so we just waited until this weekend,” said Falkowski while browsing items Saturday at Old Navy on Market Place Boulevard in Cumming. While public school students headed back to class on Aug. 9, Falkowski said her children, who are home schooled but go two days a week to a home-school group, won’t begin until Aug. 21.
