I bought the Audio-Technica ATH-M50 Professional Studio Monitor Headphones (with Coiled Cable) from one of Amazon‘s Black Friday’s lightning deals as well. Got it for US$99.99 (S$126) including shipping because it also qualifies for AmazonGlobal Saver.
In Singapore, the ATH-M50 is retailing for S$238, so you just saved S$112!
