I buy some roadmaps probably every 10 years or so to make sure mine are up to date and not too beat up, I keep them in my car and do use them occasionally. I usually have 3 maps, a local maps of my nearest city and surrounding area, one of my state, and then one of the surrounding region.
I also tend to pick up free maps wherever I can, lots of state parks and such, tourist maps, etc. but I'm not buying them so not exactly relevant.
I also tend to pick up free maps from AAA since I'm a member whenever I'm going on a road trip, I'm paying for the membership so I guess in a sense I'm buying them, but also not really
