Yeah I don't get why someone would join here just to find out how to get a hold of GunBroker, they don't even sponsor this site?
And that must of been one hell of a sale or a lot of items sold, it's 2.5% up to $1000 and items over $1k is the 2.5% for $1000 and 1.25% on the balance over $1k.
Example on an item that sells for $1500;
1000 x 2.5% = $25
500 x 1.25% = $6.25
So your fees for selling a $1500 item is about $31.25 (options like bold or colored text, or a lot of pictures is extra).
That's got to be about 15 $1500 guns sold in one month, that's like $22,000 worth of guns
