It could be, but some WMs are weird like that. We had a Target here in MN that was selling TAC figs for $2.50 for about six months or so back in the day. That store got continually raped by a few of us.
There was a Wal-Mart in Grapevine that had 30thAC figures marked at $3.00 even for about 5 or 6 months (basically from about wave 01 through wave 05). I bought so many Stormtroopers, Death Star Troopers, Honor Guards, Airborne Troopers, and Galactic Marines over the course of that time... It was awesome.
As for the Scum story, all I know is that they have an April Fools gag up there every single year and I don't see anything else that qualifies, so I've got to assume for now that this is it, and if it is, it's lame.
