Yes you can. Go to store and go to the customer service counters and they should be able to help you. At least i have gotten spare parts there previously.
Small parts, for assembly they will typically have in customer service. Other parts you have to order with customer services help.
Screws and such they have. If you are talking furniture parts. Not even north american furniture stores do that as far as i have ever experienced.
You have to go to the store. Usually all of their furniture have multiple parts and the parts are available in the warehouse. But i am not sure about screws and fixtures - why don't you call them and ask?
You cant. Sorry bud
