Some money with the first aid recipe.

[DrPieper]

I had something usefull.
I know this works for the horde.
Go get this book from the vendor in outlands and put it on AH for about 15-20g
Master First Aid - Doctor in the House - Item - World of Warcraft
It will sell.
15g profit for everybook you put on it.
Some people dont have Burning crusade i think so they cant get the recipe,
so they need to buy it from the auction.
I dont think it will make massive of gold but you can make 100g+

Well the people do have TBC but the fact is some people are either too lazy to look it up or go there and just consider spending the 15g a more worthwhile investment of their time rather than going and getting it themselves. Good find though.

Pretty cool

Goes the same for the lower first aid books also, just with a little lower profit.

I sell the 3 lower books for 4g each, usually the same ppl will buy all 3 in 1 go.

Just dont put too many on AH at the same time.

Lol I think a lot of people already do this (when they're leveling up first-aid that is). Hell, I even did this last week though. Nice tip though.

[Truckrager]

Yeah, this kind of thing is a good money maker.

Works with cook books too. At least it worked really well during the christmas event where people were leveling cooking. Made almost 1k gold over the event selling the books at 10g per. I can still sell them too just no where near as many as i was.
