Actually I reverse haggle if they go back and forth more than is reasonable.
In other words, the price starts going up once they cross the line. I tell them: going back and forth multiple times over pricing means me investing more time. That means the price to you goes up too.
Here’s the quick response I have saved, and I edit it to match the situation. It’s my starting point for the hagglers (I often edit it to fit the context):
If price is your primary criteria, I’m the wrong Fiverr seller for you.
I’m really passionate about creating truly excellent audio. That requires a lot of behind-the-scenes work that most Fiverr VO artists don’t do, won’t do, or are not even aware of, so I’m not always the cheapest, but I will do a great job for you.
There are lots of inexperienced VO people on Fiverr that want experience, so they will provide great discounts and work cheap.
I’m focused on sellers who want high quality and their clients expect the best, plus understand that quality can require a little more investment, which returns maximum value.
All the best, I’m sure you’ll find some great VO providers on Fiverr.
The funny thing is at least a third of them buy from me anyway, and I have a VERY strong repeat business. I am very confident they are getting excellent VALUE way beyond what I’m charging, so if they want it cheaper, find someone else.
(I avoid being rude to them… I want them to return later when they have the right project that needs excellence.)
If they are being obnoxious, then I throw stats at them (I have strong sales numbers…)
