Sure, but what you are paying 1/2 for? Imagine owning a home which sells for $1,000,000. Currently you pay roughly 6% - $60,000. You pick Redfin - they charge take the money and give you back 1/2 but you are still paying them $30,000!!

But if your house is sold for $100,000 you'd pay $6,000 or $3,000 to Redfin. The whole thing is just the biggest currently running scam that I can think of and someone will come along and totally disrupt this entire industry of scammers :-)
