I called yesterday looking for the mono PM since I've had no luck stalking the website, and the woman told me that they were no longer taking names for the waitlist and it was no longer being produced. I told her I had thought the regular mono version was a permanant item and she said no. I had a mini freak out inside, but calmly asked her how I could possibly get my hands on one. She said they are coming out with new versions in the future, so that would be my best bet. -____-
So I decided to call again this morning, and a nice gentleman helped me and he put me on the waitlist! He said it would be about a month, so we'll see. So maybe try calling back to see if you will get someone who is willing to put you on the waitlist. I don't know why the answers vary so much by customer service rep!
