How to make a map from lists of zip codes?

I would like to make a map, that maps out a lot of locations (100+) of zip codes - so a map of the US, with a lot of pins that point out each zip code.|||Unless you're into programming, there are programs you can buy for that. They're not cheap, though. (They're not even what most people would call expensive - they're at the "only huge companies would buy this" level.)
