This has happened both times that I have used Fiverr - pretty frustrating! This is also before I have seen their work.
You may have asked more work which are in gig or package description. Or may be seller just want some more $$$ lolx
May be you want work that is not offered for the package you have chosen so he may be sending you gig extras. Buyer’s always want work for less $$$ because after all this is FIVErr…
How can sellers up their price after accepting?
Only way the job is legally accepted is after you pay, therefore the price is locked in. Please do not argue that I am wrong. As of today, I’ve had 121 transactions on 5r.
If you were negotiating or messaging, it wasn’t technically set yet. If you disagree with the price or custom offer, just don’t accept it.
