I have a more positive opinion of Bonanza than Whateve's.
I too use the standard advertising level but find that often, items that have been found through Google shopping still cost just 3.5% fee. (I'm not sure why that is but I'm not complaining.)
Granted traffic is a lot lower than ebay but I appreciate the fewer headaches. I haven't had a problem buyer in years on Bonz and my most frequent complaint is non-payers. And with recent changes within Bonz, there's no FVF assessed until the buyer pays so there's no credit to have to apply for if they don't pay.
Like ebay, Bonanza encourages "free" shipping but I prefer to charge reasonable fees since Bonanza doesn't charge FVF on the shipping (up to $10) charges. With "free shipping," I'd pay FVF on the full price.
I average between 5 and 10 sales per month on Bonz but pay no listing fees so I don't mind my items sitting.
My main complaint is with their batch editor and duplicating listings. I don't find it user friendly (or I haven't figured out the easy way to do it) so it's quite time-consuming.
Whateve mentioned being unhappy with customer service. While a phone number would be convenient to call, I suspect it would become more like ebay, with reps reading off a script. What I like about the email communication from Bonanza, those who respond actually seem to know what they're talking about and answer the actual questions and address the issues I've asked about.
On ebay, I've found that they tend to tell callers what they want to hear so they can cut the call as short as possible, often dispensing misinformation. Bonz may take more time to answer the questions but the responses are accurate.
