Funnily enough, my father does (at the local equivalent). Surprisingly, it almost always works.

Even in chain stores for hardware/DIY or white goods (fridges, washing machines, etc) there is almost always leeway for haggling to some degree on higher priced items.

He works in the automotive industry, where haggling is basically mandatory - if you don't haggle, you are going to get shafted. Its the same at builders merchants and lumber suppliers.
