coming back and the AH pricesFollow

Sorry to start another subject about somebody coming back to ffxi, but oh well. My post is actually about AH prices since I read that erase is now going for 15k or something like that. Did they start selling it from a vendor or have prices changed dramatically in the past year? Any information would be appreciated while i wait until the beginning of the month to come back. I hope to see some familiar faces on Friday when I start again.

thank you very much
