Buying high lvl alch recipes??Follow

I recnetly got my alchemy skill to 375 and was wonderin if its worth it to pay like 500G(thats usually around what they cost on AH on my server) for higher lvl recipes like "Haste Potion" and "Heroic Potion". And if so how much do you usually sell pots like these for??

You hit the nail on the head - each server is different. Have a look at your AH and see how much they sell for where you are. Take into consideration how much you could sell the mats for and whether you'd make a profit by brewing up.

As Dlbrt said, also consider how useful they'll be to yourself, parties you run instances with and your guild.
