Price to list ad

I don't trade equipment very often so therefore I don't sell much. I did however just have an item on both A'gon & US Audio Mart. I received inquiries and made the sale on A'gon. Never heard a thing from anyone on US Audio Mart. As much as you may not like the fees, A'gon seems to be the place to get it it done.

facebook has many audio sales sites its were I buy and sell the most   https://www.facebook.com/groups/473607092676131/                                 https://www.facebook.com/groups/1598234160391737/

OK, I don't have to admit, it is obvious, but I'm a newbie here.

Is the price then 2% to list the ad, plus $4?  And it doesn't matter if it sells or not?

Or is the price $4 to list the ad, then 2% of the sale price?

I didn't see any specific FAQ section about fees, but maybe I wasn't looking in the right place.

No its $4 to post the Ad then 2% of the sale price if it sells. If it doesn't sell you are out $4.
