Jeanswest's Black Friday / Cyber Monday promotion — buy one item and get 50% off the second item when you use coupon code CM50NOV2014. Discount applies to the cheaper item. Free shipping on all orders $75 or more, otherwise $10.
I was testing this code on their New Zealand site — which has similar products, free same shipping promotion, but everything is in NZD. However the promo code has an odd behaviour there. Sometimes the 50% off would be applied to the more expensive item. Sometimes the discount does not make any sense at all. This screenshot should hopefully help explaining the situation:

Basically, $80 jeans + $20 T-shirt + discount code = $50, i.e. 50% off the whole lot. I'm sure it's an error but good luck getting some bargains this way :)
Poor coding bargains are the best.
