"Scam. They send out "gift" cards for cheap sunglasses, but shipping and "handling" charges are more than you would pay for this stuff. Their page says:
There is a 9.4% service and delivery fee per item: Includes 1st class postage, free refund or exchange program, materials, handling services and general overhead.
There is a minimum service fee on certain items - $9.90 on sunglasses/readers and $12.90 on watches.
The service fee is calculated on the MSRP (not the sale price), and is charged separately from your gift card."
