But Cyber Monday sales pale in comparison Singles' Day, a joke anti-Valentines Day turned into a major online shopping day in China by e-commerce giant Alibaba. Last year, the company's sales reportedly topped $9 billion -- and founder Jack Ma told CNBC he hoped to take it global in the next five years.
Amazon Prime Day is a little different because deals will only be offered to people members of its Amazon Prime service -- a point WalMart threw shade at while announcing its own slate of competing sales.
But Amazon and Walmart aren't alone in trying to drum up business during summer months -- both Target and Best Buy have Black Friday in July type sales scheduled for this month.
And ultimately, selling more stuff is what pretty much all sales are about -- regardless of whether they come with their own made-up holiday.
