Well i always found Big Als regular price kinda expensive. I learned to barter from mama. So i go to this neighbourhood chinese run aquarium store. I kinda watch some of their regular customers for a while, then i realized their were two prices one for them, those who can speak chinese and another inflated plus tax price for the non-speaking chinese. I became a good customer and got the tax discount for cash. And every once in a while if i am making a big purchase i'll be bold enuff to ask for an additional discount. Usually this means a few extra fish. Or try MOPS online excellent prices!!!
