That's the funny thing about biglots. I have two in my area and two out side of town and they always differnt merchandise. Last year they were selling the 4 AMT car kit value packs for either $9.99 or $12.99. I picked one set which contained, a Catalina, a drag nova, an old Chevy stepside pick-up, and a third kit I cannot recall at the moment...
They don't often get models but when they do they are pretty cheap. They also have a few die-cast kits on the shelves at my local BL too but none I'm interested in...
