Water refill station for 5 gallon jugs near tmc?

I recently bought a water dispenser but I've been having a hard time finding refill station. I live 5 min from RIce and tmc.i went to several heb (meyerland & buffalo speedway) and two kroger (kirby) but I couldn't find one that let's me refill water for cheap. I don't really care which brand of water but I just want to refill for <$2. Thanks
