"Every time I order contacts through visionpros, mysteriously and miraculously an extra box of contacts ends up in my cart right before I check out. Good thing I look over what I'm actually about to purchase or who knows, I might be getting charged for something I didn't want. It took me at least 20 minutes to order 2 boxes of contacts because of "internal error" during the very last step of checking out which directed me all the way back to the sign in page so I could start my order completely over (or maybe I just got charged twice). Still, more convenient than having to drive to a doctor's office."
