Amazon is rearing to go with its once-a-year shopping holiday, Prime Day, with serious discounts on many of its services as an online retailer. Want Amazon Music Unlimited? Now is your chance to get a four-month subscription to the music streaming service for just $1 thanks to their special offer. The deal ends July 11th, and you must be a Prime member to take advantage of it. No worries though if you are not, because you can still sign up for a 30-day free trial of it anyway.
