I was supposed to be charged $6.99 for the first 2 sets of windshield wonders that I ordered and the 3rd set was supposed to ship at no additional shipping cost. Yet they charged me $34.95 for shipping...over-charge by an additional $20.97. The customer service link gives hours of M-F 9 - 5 yet they tell you they're lines are always busy so it's best to call on Thurdays or Fridays. It's Friday night now (10PM) when I placed this order which means I have to wait almost a week before I can maybe get through to them. I'm filing a complaint with my credit card company.
