Wow. Sorry Redmao, but the 2008 Universe line has pretty much cleared shelves aside from a few Silverbolts at some Zellers. Acid Storm is sadly long gone, which is sadly to be expected from a two-year old toy these days.
([old man voice]I remember back in the mid-90s I could still walk into a store and find an X-Men figure originally released two years prior. Or an older Beast Wars figure. Stupid things today changing.[/old man voice])
EDIT: Have you tried Legends or Toys On Fire? Honestly that'd be your best bet.
