The major reason why I'm submitting this review is because I feel the service and value for money at Selby's is pretty much unbeatable (eg. picked up these headphones for about 30% less than could anywhere else in Aus). Never been disappointment with any purchases made through Selby! Thanks team! (Posted on 9 May 2017)
