Need help with donations for coins, and the amounts per dollar and stuff.

So I'm curious exactly what the rates are for donations to coins and what not? How many coins per dollars? I am USA currency by the way. I did not see any section on the site or forums that has this. If I missed it, please shoot me a link, or if you know the exact amounts, that would be great! Also I've seen players with heirlooms on IDK if that's something you can donate for, or use coins for? I saw lots of epic gears and mounts and profession things but did not see any heirlooms. Would love a quick rundown on all that please, & thank you for any help!!!

When you agree to the terms and select your donation method here: https://www.warmane.com/account/donate it tells you exactly how many coins you can get. On top of that you get a small extra depending on your donation rank that you can find here: https://www.warmane.com/account

You can buy heirlooms on Icecrown, not sure if it's with points or coins though. You'll have to check manually since I don't play there.

Thanks for the info, its def a lil more expensive than I woulda liked, on top of that It said there was no payment methods in my country and I'd have to send a request of some type, so prolly will just tough it out.
