After months of waiting, Amazon Prime Day is finally here–and it's arguably the e-tailer's biggest sale yet. Now through Friday (yes, Friday), the Everything Store has unbelievably epic discounts on everything from air fryer to affordable, game-changing tools. But are they actually too good to be true?

As editors who spend our days scanning the web for the best deals, we approach most big sales with a healthy dose of skepticism. We mean, it's easy for a retailer to call its own sale the biggest, best one yet, but is it really? However, when we crunched the numbers, it turns out there are a bunch of Prime Day deals that are actually cheaper than Costco. It's no secret that Costco is *the* place to go for budget-friendly bulk items and well-priced essentials, so finding items that are cheaper than the wholesaler's rates is huge.

To help you walk away with the very best bargains, we compared Amazon and Costco's offerings to find the top Prime Day deals worth adding to your cart. Since Costco is known for selling large quantities for a fair, affordable price, we compared quantities to ensure you're actually getting the best value. But hurry: Whether you're stocking up on pantry essentials or want to refresh your cooking tools, we have a feeling these deals will fly off the virtual shelves. On your mark, get set shop!
