Can #BuyNothingDay put a dent in our fast-fashion addiction?

London - 20 percent discount at Asos under the codename GoGoGo. 30 percent discount at Levi's. Urban Outfitters and Monki offer 50 percent off on selected lines, while H&M goes for up to 60 percent off, following its 20 percent off promotional offer. All weekend long, these fashion retailers have been flashing their tantalising discounts at me, teasing me with the promise of a great deal via email, encouraging me to score a great deal through Facebook and making sure I don't forget it's Black Friday, which means extra discount, using push-notifications.
