Online marketplace Bonanza announced today that it celebrated its one millionth registered user this week. To celebrate, sellers organized a give-away contest to promote their stores, with over a hudred sellers offering gifts for the one millionth member.

The company, formerly Bonanzle, says it has seen steady growth in membership, traffic and revenue since launching in 2008. It attributes this mainly to its fee structure.

“We’re happy to let Amazon and eBay argue over whose pricing scheme is ‘best for sellers,’” said CEO Bill Harding. “Meanwhile, our fees average 70% lower than theirs. We aim to make selling online simple enough for my grandma to do it, and yes,
that ‘one million’ number includes Grandma Harding.”

eBay announced last week that it is launching free listings for all sellers.

In 2010, Bonanzle acquired artisan merchandise site 1000 Markets and changed its name to Bonanza. The combined company would take aim more at Etsy than eBay, specializing in “unique and non-mass-produced items”.

Etsy had 1,025,124 new members join in February alone. The site saw 1.49 billion page views during the month.
