I do the same. Loads of cross-faction transfers and we've never been snipped.

I always coincide my neutral transfers with money transfers. Say my Horde buddy needs to borrow around a 1000g and I need to move an item to my Horde shaman (like my Tankards O' Terror for upcoming transmogrification). I'll just use my buddy, post it up for 1000g, I get the item, he keeps the gold. Win-win! That way no one will snipe it.

What are you going to spiff the Tankards into?

@Cambro

No my friend, you misunderstand! I'm spiffing my axe/mace combo INTO tankards! HUZZAH! No goblin shaman (or dwarf shaman) should be without his TANKARDS O TERROR!

Wow... for some reason I cannot say
"You mean 850g since the neutral AH takes a 15% cut..."
but my stupid "test" post goes through?

Damn you

Indeed. We've usually done this side-by-side or over the phone whenever possible. Esp before faction transfer. My bf and my best-gaming buddy both had alliance characters with well established inventories and gold that needed to be transferred. We were highly paranoid about it, so I was on refresh duty while they posted.

I use this method (with the friend on Ventrilo or Mumble, so the coordination is even easier), or an alt on another account (back when I had two), with both accounts logged in simultaneously in separate windows.

In what's probably hundreds of cross-faction transactions, I think I've had exactly one auction sniped, and that was a mistake on the part of the buyer--they immediately tracked me down and returned the item.
