SG&A expenses increased by $10.3 million, or 134%, to $18.0 million, as compared to $7.7 million during the same period in 2011. $5.4 million of this increase is due to the addition of the SBT stores, while the opening of four new non-SBT stores added $2.2 million in the current year, due to increased advertising, salaries, payroll taxes, building rent and other costs.
