@RJ I posted:My suggestion is to go to your local drug store (CVS, Walgreens, etc)., an art supply store like Michaels, or even a store like Target or Walmart. They always have a small stack of diecast vehicles in a corner somewhere. Although they will not all be 1/43, 1/48, 1/50 scale, I can usually find one or two. For over a year every time I could go into one of those stores I would pick one up for $6 and by the end, I had enough vehicles for my entire layout.
A few years ago Walgreens replaced all the Rite Aid stores in my area and Rite Aid had a huge sale since Walgreens wasn't using any of the Rite Aid inventory. The rack of 42 cars (yup I counted them) was reduced to 50% off. Most were 1:32 scale but there was about 10 that were 1:43. Well after two weeks there were still 42 cars on the rack. i found the store manager and ask what happens to the inventory when the store finally closes. He said that most of it will go to other stores but the remaining inventory will probably end up in Lot type stores. For the heck of it I offered him $25.00 for the whole rack of cars. He said SOLD but you have to take the display rack with them. Well I kept the 1:43 cars and sold the rest of the cars along with the display rack to a flea market jobber for $100.00 .
