Looking to sell my remaining exam vouchers

I completed a vocational IT program that included several CompTIA exam vouchers as part of the tuition. I already have certs (CCNA,net+, and security+)so I’m not planning on taking some of the remaining cyber security focused exams. My school buys these vouchers and just gives me the codes. I asked around the school and some of the students have already sold some of theirs. Looking to see if anyone wants to buy them
