They don't normally get sold at that size in my area so I'm not sure if it is a good price or not. I don't think $99 is unreasonable for a healthy bichir that size but you can probably talk them down a bit. To give you an idea I paid $80 for a 12" lapradei. If space is an issue I probably won't get it as someone noted that they can still grow a few more inches. You might want to look at juvie ornates and grow them out yourself.
