Looking for Romantasy Recommendations

I am wrapping up on the ACOTAR books and found them to be amazing. The romance was steaming, the drama was dramatic. I am now at a crossroad on if I should pick up the Throne of Glass series or something else entirely. So… just looking for some recommendations. (Smut is not a must but a definite plus.) Also, if anyone knows any used books sites that are affordable? I used world of books to get ACOTAR but its almost 150 dollars for TOG. Thanks in advance for an help!!
