Buying frozen fish is usually significantly cheaper than getting it fresh. It also means you can store it for much longer and you don't need to cook it all at once.
Going to local store is sometimes cheaper than mainstream supermarkets. We're based in Portsmouth which has plenty of places to go to get fresh seafood - which can be extremely cost effective. If you're at a coastal uni, it might be worth exploring.
Keep your eyes out for special offers on seafood. It's a great excuse to try something new. If you aren't sure how to cook certain types of fish, take a look at our recipe archive or do a quick Google search for inspiration.
