The fees are like a percentage of the final selling amount for each item...I sold something for 600 and my fee was 15 bucks....
They let the seller and buyer contact each other to handle payment, so if both are good with paypal, then its a go! I just got 'gifted' a paypal payment a few mins ago for another item...
So you just pay an FFL dealer to ship for you to another FFL (for firearms) or you ship yourself? Any gotchas or stuff to watch out for besides the obvious law/regulations?
