I found Furla sunglasses on sale in the Peoria Costco for $44.97. I don't see this style on the Furla website, so maybe they're last season's. Don't care, like them anyway.
Kirkland sunglasses were on sale in Peoria and Nashville for $22.97. This is a great price; I have these, paid full price, and like them.
At the Brentwood, Tennessee, Costco, Chrome Heart Orbi sunglasses were $229.99; looking on-line, these sell for around $500 retail. Brentwood Costco also had Mont Blanc sunglasses for $105.99.
Nashville Costco had Armani and Fendi sunglasses for under $60.00. I'm guessing the different Costcos got different selections, so if you're in the market, you might want to check and see what your local Costco is carrying.
All Costcos seem to have a new sunglass product - reading glasses with sunglass tint. Sunglass readers is a great invention for those who love to read around the pool, but need the amplification of readers. For the few times that you need to read outside, this is a small investment to improve vacations.
