Online retail giant Amazon will celebrate its 20th anniversary next week. To mark the occasion, the company has announced plans for a massive sale–bigger than Black Friday.

For one day only on July 15, Amazon will introduce “Prime Day.” The retailer is calling it a “global shopping event” that will offer “more deals than Black Friday.”

As its name suggests, the sale will be exclusive to Amazon Prime members in the United States, United Kingdom, Spain, Japan, Italy, Germany, France, Canada, and Austria.

Deals will start at midnight on July 15, with new offers coming online as frequently as every ten minutes. Amazon did not say what items will be discounted, but you can pretty safely assume video games will be on sale.
