At the time, grocery stores would cash your paycheck for you without taking any fees. I usually bought a few groceries, signed the check over to the store, and got the difference back in cash. This was 5 or 6 years ago, not sure if it's still do-able. No harm in asking though.

Check cashing places are of the devil, and a great way to prolong your financial trouble. If possible, try finding a friend or family member willing to cash your checks for you instead.
