If your purchasing large items that you use alot, buy it in bulk. If you buy more it will cost you less in the long run. Example. Buying printed checks at a min of 250 qty, can cost $.15 each vs 3000 qty, at $.08 per check. Same thing for bulk blank checks or paper for your business. It may cost a little more for shipping, but it will still be cheaper.
Its always good to buy from a vendor that you have a great relationship with. That way, if you need the item quickly, and they know your a repeat customer, it can be shipped same day or next business day. Ask your vendor if they can offer you any discounts once you reach a certain amount of sales. Some business actually does that.
