I have used Bonanza for years and would not hesitate to buy there as long as I used PayPal for my own protection.
For sellers, the site used to be exceptional, with speedy, human customer service. But now Bonanza has added a penalty fee for sellers who don't purchase their shipping, which they claim is the lowest around. Don't be fooled; it's not even close to the lowest.
They also claim they will refund you if you buy their shipping and find a lower-priced service elsewhere. I'm still waiting for that refund to appear.
And, just to solidify Bonanza's standing as Worst Shipping Ever, when you do buy their shipping, they add a $2 charge, which will be put toward the next shipping you buy from them, so "you're really not losing anything." As if. When you use the $2 they stole from you to buy a new shipping label, Bonanza will take another $2, so you'll never really get that money back. It's just a kind of blackmail to force you to buy their shipping.
Imagine going into Walmart for a pack of Oreos and finding a two-dollar charge added on.
"What's that for?" you ask.
"Don't worry, the next time you come in, we'll apply that $2 to your purchase."
"And then you'll charge me another $2 for shopping in your store."
"Basically, yes."
Let's face it, if Bonanza really did offer the cheapest shipping around, would they have to use extortion to get sellers to buy it? We'd leap at the chance to save on shipping. The fact that they have to force us to use it just proves it's a bad deal.
So, buying on Bonanza? Go for it. Selling on Bonanza? Be wary.
