I was lucky enough to really get obsessed with polish in 2010 and was able to stock up on some of the OMG holos before they vanished/started going for crazy prices. I found IDK, LOL, 2NITE, GR8 and TTYL on ebay for highly reasonable prices. $4 each and $6 for TTYL...yes please. I was rather lucky. I thought I'd be happy if I managed to get 6 of the collection. So when I saw L8R G8R and FYI on trade me I only bought L8R G8R. I have always regretted not buying FYI.
So I took the plunge and paid an inflated price on ebay and now I own FYI and have no regrets.
