Used Book in Good Condition
The book Combinatorial Problems and Exercises has a lot of really good problems which range from fairly easy to rather challenging.
Personally, I enjoy https://projecteuler.net/archives (but understand, that for some problems, you would assume that the computation power you'd need is really large, however, there's almost always a more elegant solution.)
If you get bored with that, I'd really recommend https://www.amazon.com/Combinatorial-Problems-Exercises-Chelsea-Publishing/dp/0821842625. The book is absolutely incredible and there's a rumor (unconfirmed) that if you're a grad student in Hungary and you're unable to solve all the problems in this book, you should quit grad school. (I'm aware this is a joke, but given the number of brilliant mathematicians who were from Hungary, I'm not so sure anymore)
