Planetlulu.com
Planetlulu.com, founded in 1998 by Noah Soltes, is an American website notable for originating what would later become known as "online flash sales." Planetlulu.com drew inspiration from sample sales and duplicated the sample sale experience online. Dates and locations of sample sales were announced and held monthly or biweekly.
By 2002, PlanetLulu.com held invitation-only sales seven to ten days a month. The site sold a limited amount of items in each sale and featured a "“Nab-O-Meter" to tell users exactly how many of each item were left. In 2006, PlanetLulu.com was featured on The Tyra Banks Show.
