想問去豐澤同百老匯買相機包唔包電池，充電器?定要自己另外買?

Both are yes.

Whether an electronic appliance includes accessories is totally up to the manufacturer, not the retailers. It does not matter where you make the purchase.

However, the accessories included are only basic. In the case of camera, most people will generally buy an extra battery just in case.

當然包，賣全套，沒有分開賣，全套貴好多
