PC Sega Smash Packs

Does anyone here have any idea as to where the two Sega Smash Packs for PC can be located and grabbed? (Whatever way of getting them, with moolah or without).

Just thought I'd ask. :)
Last time I looked, the bigger stores that carry computer software like CompUSA Wal-Mart Supercenters, etc. (even Office Depot IIRC, might have been OfficeMax) have at least one of them, for about $10.
