Currently, Amazon has discounted the price of a three-month Xbox Live Gold Membership to just $14.99. That's down from $24.99, and brings it back down to its all-time lowest price, and definitely worth picking up.
With the Xbox Live Gold Membership, you'll be able to play multiplayer games online (without them being physically with you to play, like in the old days). You also get free games each month, and can save between 50% and 75% on newer games. Which makes this more than worth the price, since the free games themselves are valued at around $700 per year. With this three-month membership, you can add them onto your account and be good for even longer. Now if you already have a Xbox Live Gold Membership good through the rest of 2018, you can still pick up a three-month membership here and add it onto your account. You can add up to 10 years of Xbox Live Gold.
Now this item does not ship, it's a digital product, and you'll get instructions on how to use it in your email after your purchase. But you can still sign up for Amazon Prime, which includes free two-day shipping, and pretty cheap next-day shipping if you need it here extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime by hitting the link below. You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year. Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
