Dropped by the Levis store at the DFO at South Wharf and they had a further 50% discount off some of their already discounted jeans styles. I got a pair of 315 Shaping Bootcut jeans; they were originally discounted down to $59, so the additional discount brought them down to $29.50. These are extremely comfortable jeans - like the stretch jeans of my youth. They have a bunch of different styles so it might be worth a look. The 315s sell for roughly $120 at Myers. (I got a black pair).

Don't know how long this is on for and exactly what styles were there. There were discounts in both mens and womens jeans.
I put in the link for the opening hours as they don't have an ad for the specials.
Do you mean South Wharf?
