Excited Daughter
I bought these glasses for my daughter and she is thrilled with them. Loves the color scheme and the clarity of the lenses. Costa fan for life!

First Pair of Costas
I have tried on a lot of them but never pulled the trigger to buy them until now. Provengo makes it so simple to get the discounts we deserve. The sunglasses are great and I have already worn them a bunch. This is not some knockoff junk. They are legit.



Love the Stylish New Readers
The glasses were a good value and look great. The built in readers were not something I would have automatically looked for, but now that I'm using them it means I don't have to take my sunglasses off to read a book at the pool. Good stuff. PW
