Was just at my 2 local Walmarts...I honestly dont think they would clearance them because I dont think the UPCs changed. So "they" are probably blissfully ignorant as to whats actually inside the box.
I found a bunch of wire-backed XG2, but someone in another thread mentioned the XG2 might not have lost its wire-backing. Seems odd, but I now have 4 years worth of OG Ultras in XG2 (I only use 1 per year). For shiggles I may go back and buy more.
I did not check the filters for my G37...its smaller and I forget the number but I doubt I get lucky with that one.
