There's tons of free ones on youtube so there's no need to spend a bunch of money. Proko has some good stuff on his channel. He does a lot of comic book stuff but he's a classically trained artist. Pretty sure he's got a beginner's section. He also has some videos giving advice on learning resources. There are lots of others that are really good too.
Drawabox.com has some good free stuff too.
If you'd prefer books I think Andrew Loomis books might be public domain. Fun with a Pencil is a good one. If they aren't public domain you can get them for $10-15 on Amazon because they started reprinting them.
How to Draw Comics the Marvel Way is also a really good introduction to drawing. Don't let the title fool you though because its one of the best beginner's drawing books regardless of the genre.
Those are just examples though, there's tons and tons of great resources and everyone has their favorites.
