I was very impressed with the level of knowledge that they had about different types of contacts. They were so helpful that they even recommended a brand that they thought would be appropriate for my lifestyle. They are WAY overbooked and the staff is clearly overworked and not always that pleasant. I've never been in there when the waiting rooms weren't packed with a bunch of very aggravated people. They seem to be more concerned about quantity of business over quality. I feel like they always have a special going on every time I visit. Even if I don't bring in a coupon the staff will inform me of the promotions they have going on so that I can save money. They've never used foul language, which has bothered me at some of the other places I've been too. They always make an extra effort to be polite and courteous.
