Amazon Prime Day has become an unofficial shopping holiday, and other retailers want in on the shopping frenzy. To combat Amazon's dominance, online retailers like eBay, Macy's, Best Buy, and more are creating huge sales of their own. By shopping these sales, you can save on tech, apparel, and home goods — without paying a pricey membership fee. Since its introduction in 2015, Prime Day has transitioned from being a day to find decent deals on Amazon into a massive day-and-a-half-long savings event.
