Also a reason to pretty much never go with GoDaddy, since they're kinda infamous for doing this sort of thing (and the experience once you do sign up with them isn't much better).
Pretty sure I've had this happen before because I've used GoDaddy. Never with any other registrar.
It’s fine if you use ethical registrars like hover or namecheap.
I've had namecheap do some "shenanigans" where a domain will be listed for once price when searching and suddenly jumps up significantly when you try to register it.
