As far as lines costing so much....5 years ago I was top sales associate and made top pay at $9. an hour. Now I am just an associate and started at $11. Wages go up, cost of merchandise goes up. Specialist to design these materials and tapers wages go up...on and on. I remember when gas was $0.59!!!!
