Amazon's Prime Day is here, and let us tell you something: The deals this year are really, really good. How good, you ask? Well, for starters, cheaper than those at Costco. Whether you use your Gold Star membership to buy daily essentials in bulk or splurge on a sleeper chair or a tiny house, the wholesaler always delivers excellent value. But while there's always a time and a place to indulge in a Costco shopping spree, Prime Day is not one of them. We did the math and, over the course of the multi-day shopping extravaganza, you can actually buy similar items at Amazon for a lot less.
With thousands of deals to sift through, Prime Day shopping feels like the retail equivalent of drinking out of a fire hose. Not only do you have to figure out where to begin your search—there are bargains on everything—but you also have to suss out if what you're adding to your cart is actually a good deal.
That's where we come in. To help, we found 18 standout deals that are actually better than what Costco has to offer. And before you even ask: Yes, we compared the quantities of each item to make sure you're walking away with the best bang for your buck. (Even Costco's bulk items can't beat these Prime Day bargains.) The list below is stuffed with everyday essentials you'd eventually need to replenish, like pens, toilet paper, and hand soap. However, Prime Day is also an opportune time to buy a new toolkit, knife set, or Brita filter. Either way, your e-cart and wallet are both about to be very happy.
Say goodbye to mess with Seventh Generation's all-purpose cleaner. At nearly $18 for four 23-ounce bottles, this option actually gives you more for less than what Costco has on its site.
Speaking of cleaning, now's a good time to pick up some microfiber cloths. These tiny towels do an excellent job at picking up curbs and spills—not to mention they're reusable, making them a solid choice for anyone who wants to cut down on waste. While Costco sells an eight-pack of microfiber kitchen towels for $19, you can get a dozen at Amazon for $13 less.

Best of all, the Brita pitcher is nearly $20 less on Amazon than it is at Costco.
