There are a LOT of complaints from the BBB about Bonanza right now over the last year. Sellers getting charged for things years ago, customers getting ripped off regularly. Just really, really bad image. The responses are really template responses too.

It seems like the Bonanza owner put his all into the Vercado webstore builder and wanted to capitalize on the thousands of Bonanza sellers to build that platform, but nobody wanted to use it because it was too expensive at $100/month. Now he's finally realized it, and has reduced it to $35/month. Sadly though, the community of avid members and sellers have dwindled far down from the highs. I even left 2 years ago and ran my business on eBay until I saw market trends shifting away from my products. Now, with little in house inventory, I have been looking to rebrand into a similar but new line and move back to Bonanza.
I was going to shoot for adding products and rebuilding my rebranded store, but not sure now. I know a lot of people in the same boat, so this is my input.
Some free alternatives are:
Odoo.com: Great themes, free store. You can select one app free, so select "ecommerce" for your site. Other features available for a fee.
Ecrater.com, which has marketplace sale fees but no direct store sale fees. In business since 2005, not likely to up and vanish.
Square Online (squareup.com) 100% free except payment processing. Also has more options for a fee. This is a publicly traded company, and probably won't go away anytime soon.
Also, freewebstore.com allows you to build an unlimited free store with Paypal only for payments. Has upgraded stores for a fee.
Gumroad: Free store, but has a 10% fee for direct traffic, marketplace sales though are 30% fees.
