If anyone's looking for cheap(not cheap, but cheaper than holt) designer sunglasses, go to skylight optical (not sure if skylight is the right name, its the place in lansdowne with everyone wearing white lab coats).
Go see the sunglasses and ask to knock 1/2 off the price tag
helps if youre chinese.
Got my guccis suuuper cheap, can't remember how much but it was a lot less than holt
