FSBO: is two prices normal?

[Susan H.]

I've been communicating informally with a person who lives in my neighborhood. She's a Realtor and co-owns (with son) a rental close to one of my own. She's thinking of selling (not yet on MLS) and said she'd give me a selling price after running comps (reasonable). Her quoted price was right in line with comps and I told her I'd like to schedule a time to see property with my agent. She then said she was not going to pay any Realtor fees and would go FSBO. Said if I wanted to involve an agent she would quote a different price.

Is this a common practice?
