You give few details on your background.
Keep in mind that for many classical physics is interesting primarily for historical reasons and to teach serve as background for modern physics.
First I would recommend
Theoretical Physics by Georg Joos
It covers a broad overview of physics and cost ~5$ so it is a good supplement.
For mechanics I would suggest
Classical Mechanics by Herbert Goldstein, Charles P. Poole Jr. and John L. Safko
Some would say an easier book should be read first, but I find it very accessible and adequate in coverage of basic and essential topics. Many of the easier books omit key material or offer poor explanations and you will want to read Goldstein after anyway.
A more mathematical if quirky book is
Mathematical Methods of Classical Mechanics by V. I. Arnold
For electromagnetism it is a bit different as several more advanced books claim to start from the beginning they are lying so a basic book is helpful
Introduction to Electrodynamics by David J. Griffiths
despite some flaws is a good first look (skip all the remedial calculus parts if you do not need them)
Several books you might like to look at that have been helpful to me are
Classical Electrodynamics by John David Jackson
You will probably like to look at this so you won't feel left out when physicists talk about it. It is prized for its mathematical calisthenics and confusing incomplete explanations.
Principles of Electrodynamics by Melvin Schwartz
Very good especially on relativity
Electrodynamics and Classical Theory of Fields and Particles by A. O. Barut
This book is very nice and makes up for the lacking coverage or absence of a Lagrangian-Hamiltonian formulation for EM in many of the other books.
Classical Electricity and Magnetism by Wolfgang K. H. Panofsky, Melba Phillips
Covers well several topics left out of other books.
Electrodynamics By Fulvio Melia
A book that gets to the heart of the matter
The Electromagnetic Field by Albert Shadowitz
as mentioned above is pretty good
A note on price I paid more for Goldstein that all the EM books listed combined, party because I bought older used editions of Griffiths and Jackson. I have not read all of them all the way through, but they complement each other well.
Of course I must mention that (the relavent volumes of) Course of Theoretical Physics by L D Landau and E.M. Lifgarbagez is a well deserved classic, though not for most people an introduction or only book.
