For Sale by owner to be listed in MLS

I came across this site, have any of you used it? Does it work? They will put your home in the MLS for a flat fee, no commission. Thanks, Amy

I don’t know if it is the same franchise but I have use flat fee listing in MLS for as little as $199. They call you if needed but the realtor calls a centralized showing system. I have use 1% brokers and other arrangements to put in MLS. Sold some others are pending. The selling agent /broker will still get their 3% fee.
