I was wanting to purchase some liquid Tide for the washing machine at my apartment complex. Having minimum funds because I'm on disability, I need to always look for the bargain. The detergent that I wanted to purchase is twice the price of h e detergent. We have old washing machines in my building not high efficiency. I shouldn't have to pay twice the price for the same detergent because I have an old washing machine. What would be the solution? I don't want to use anything but Tide. I want either the 150 Oz or 200 oz bottle. Thanx
