It appears that most walmart's are set up on the same floor plan, so they should be near the Tonkas and R/C toy monster trucks. At least that's where they are in all the WMs in metro Detroit, and they have a couple 1/48th P-51 kits (monogram) and maybe 50 car kits (1/24 and 25th). No paint or accessories.
And Goose, the internet murdered the local hobby shop.
