On July 15th, Amazon celebrates 20 years of online shopping. To celebrate, the biggest box retailer is celebrating "Prime Day," a sale set to rival Black Friday. That is, apparently, a good thing?

The so-called “global shopping event" will only be available to Prime customers in the United States, the United Kingdom, Spain, Japan, Italy, Germany, France, Canada, and Austria. There will be flurries of deals every 10 minutes! Hooray!

Except, before you celebrate and fill your house with more plastic, let's take a closer look at how a monstrously-sized business like Amazon is able to offer huge discounts on popular products that still make it to your house in a day or two.
