9v batteries

My portable digital radio is the best thing since sliced bread I reckon. The sound quality is the best bar none. No more static noise and interference you get from an analogue radio, just pure sound and sweet music. The only drawback is that it goes through batteries very quickly so I have to continue swapping batteries every eight hours. Therefore I have to keep buying batteries every few days, I have a shop that I go to all the time for my batteries in my local neigborhood. They sell all sorts of batteries even the odd ones and the 9v batteries that some equipments need.
