Where can I find old newspaper ad inserts, like for grocery and drug stores?

Question

I'm trying to research frood and drug store prices going back decades. The newspaper insert ads for such stores would be a logical place. The regional newspapers offices say they don't keep that information, since it's up to the ad buyers to do that. The stores' offices say they don't keep their old ads on archive, either. And the public libraries say they 1) throw those ads out, and 2) never microfilm them for the archives, both to save shelf space and processing time. Are there any places I should ask?

Answer 1

You can go to any store and tell them what you are trying to do they will give you the old one that the people didn't buy.
