So whats the skinny?

Holy crap 1200 each *whistles*
I remember on my original druid I just used travel form for the longest time cause I couldnt make the 100 gold for the slow mount.

Definitely worth the money to level 15% more quickly though... do they work til 85?

The helm and cloak heirlooms do work until 85.

Edit: If your accounts are on 1 battle.net account, you only need to worry about getting 1 toon to the guild rep to buy them. Most of the heirlooms are going "Battle.net Account bound" in 4.1

it would be nice if they boosted the old heirlooms to go to 85 as well in 4.1.
