Found the Target Ex. Clone at Brentwood Target on Saturday and I've heard they're showing up all over the place. (but selling out quick, I bought 4 myself)
I've also got a freind who found 41-44 at the Eureka Walmart and another friend who found them at the Granite City Walmart. Both Saturday morning. The Eureka store apparently had 20 or so cases with them, so it may be worth a phone call to see if they have any left.
