Any feedbcack on discount RE agents like Redfin vs FSBO?

[Andi Sjamsu]

HI Everyone, we're preparing to sell our current home.  I have a few private parties expressing interest, showed it to 1 prospect already & he's applying for a mortgage.

I'd prefer to NOT have to pay a seller's commission, but just in case, does anyone have experience with like redfin etc?  I have several agents offering 5% comm (vs more common 6%), and it looks like redfin is 1%+ buyers comm of 3%= 4%, so it doesn't look like a massive savings or am I not understanding their structure properly?

Thanks
