With eBay busily destroying their reputation and driving sellers away from their platform, it is becoming increasingly competitive for marketplaces such as Addoway and Bonanza to fill the void. One huge benefit of both Addoway and Bonanza (and eBid) is that they do not impose ridiculous seller account limitations. This means you can work hard to produce a large online store and not be dictated to in terms of the number of items you list for sale.
Bonanza and Addoway are also conscious of the importance of social media and have done well to allow store owners the opportunity to promote their booths using Facebook, Twitter, Pinterest, Stumbleupon and Digg. This is also a fun aspect of selling and lets you learn more about how to engage your target markets. With oohyey.com I use as much social media to demonstrate new and unique items on a daily basis.
Both Bonanza and Addoway are easy to use. They have great user interfaces and both have demonstrated to me good customer service levels with all inquiries handled quickly and efficiently. Their listing import tools are very useful and save a lot of energy and time, which is really important for store owners. The only thing lacking according to reviews of both websites is the lack of promotion by both marketplaces.
Given the number of online tools these days, all shop owners should be busy promoting their stores and products! There is no excuse for lacklustre efforts in this department and you cannot lay idly by and expect Addoway and Bonanza to do all the work for you! Marketing is something you should be constatly working on, adjusting, improving, learning about and trialling new resources at every available opportunity!
As for which marketplace is best, I have no preference. Both Addoway.com and Bonanza.com are equally good and I think more and more online buyers and sellers will take up accounts with them over time. But we sellers also need to be aware of the need for continual and consistent effort to promote these alternative marketplaces, as well as our own accounts! Tell friends and family to list and or buy product from these venues, as they are excellent viable alternatives to you-know-who!
