The self-service lockers require exact change. Since we needed the service on the last day in Prague while trying to spend our last Czech crown, we did not want to hassle with getting small changes. We used the left luggage room instead.
The left luggage room is situated in the same hall with the lockers. Rates are charged by the weight of the luggage: 15CZK (52 cents in Euro) per piece if the weight is 15kg or below, and 30CZK for anything over 30kg. This is the rate per 24-hour period.
