I went to singer specs for an eye exam they are not sure about the price they said its around $60.00 does the price change daily like oil or gold. How can a store not know the price of their products or services? If I get glasses or contacts the price might change after I order them I afraid to buy them at that store. I think a big company like that should not be so wishy washy, why are they so afraid to quote an exact price to there customers. I don’t think I want to do business with singer specs.
