I also can’t find washing soda near where I live. Someone said that they get it at Walmart, but the Walmart in my town does not carry it. I once contacted Arm & Hammer about whereI could buy it. The nearst location that they could come up with is 35 miles from my house. This was a Harris Teeter store in a high end neighborhood. The price of the soda was so high that I did not save any money making my own detergent. Is there another brand of Washing Soda other than Arm & Hammer that might be cheaper?
