Complaint Review: Costa Del Mar Sunglasses

I purchased a $210 pair od Costa Del Mar sunglasses which come with a guaranteed Waranty.  These sunglasses broke within 3 months of ownership and the repair shop attempted to get $70 dollars for repair work. 

I have been really let down by this lack of honoring warranty and would like others to know about this.  Broken pairs, of which there are many, can be bought on ebay.com for far cheaper than their repair shop.
