"FREE" MLS EXPOSURE FOR SALE BY OWNER?

[Asher Carr]

So I was speaking to a partner about a home we're trying to sell and he wants to get exposure on the MLS without the cost of an agent. The reason he hasn't involved an agent because the purchase price is not far from what is owned on the home so there's not much room to tag on a commission. He suggested looking for a free site or flat fee site to get the exposure. I've been looking for a while and no luck. Does anyone have any suggestions on this? Thanks.
