Here in sweden you can buy hikari massivore in bulk of 1kg for around 80usd. But ive been looking for cheaper pellets since i got to much fish. I go trough a 250g bag of cichlid gold sinking in one day with all my fish. So i feed my rays and all the big fish shrimp, mussels, herring and alaska pollock depending on what is cheap for the moment. I feed about 1kg of shrimp every other day atm since i bought 15kg of shrimp really cheap. And going out fishing for herring next weekend. You can always order nothfins pellets online cheaper then hikari. I find that northfin krill gold and jumbo fish goes down easier then hikari for my fish.
