Pick up Super Smash Bros Ultimate on sale with a $10 promo credit

Prime members always get the best deals at Amazon. Right now, Amazon is offering the upcoming Nintendo Switch video game Super Smash Bros. Ultimate for $56.35. Though that's only a $4 discount off its regular price, you'll also receive a $10 promo credit with its purchase if you're a Prime member. Together, those two deals make for a solid offer.

The Super Smash Bros. Ultimate Guide books are officially available to pre-order at a discount right now too. You can grab the paperback edition for $11.54 or the Collector's Edition for $30.79.

The Collector's Edition guide includes almost 150 more pages than the paperback edition, so it's definitely packed with more than just a nice binding. Ea...
