Do you know what happens to those frames that are returned during the "30 day guarantee"???
They are re-tagged and re-sold as new.
New "demo" lenses are cut for the frame (look for lenses without a logo on them) and new SKU tags are placed on them (look for handwritten sku tags).
If I'm not mistaken...this is illegal!!!
Any used product that is resold MUST state that it is "used". Lenscrafters does not due this. I find it disgusting. Would you want to purchase and wear something on your face that someone had on their sweaty, greasy face for a month??? Not me!!!
