Whenever I run out of stocks for office supplies I make sure to order by volume and I go for promotional products because I will save more money. I buy ahead of time such as during sale seasons throughout the year. I stock up on basic items such as notebooks, pad papers, ball pens, folders, envelopes and a lot more that needed in the office. And I make inventory of existing office supplies in my stock to avoid duplication when ordering. This is what I do in the office being in charge of office supplies stocks.
