If your business consumes large quantities of a particular good, knowing how and where to buy at wholesale prices can save you money.

In most cases, all you have to do to purchase at wholesale is demonstrate that you're a legitimate company and buy at the suppliers' required quantities. Some sources ask for your state reseller's license or tax ID number, which allows you to avoid paying sales tax on the items you buy at wholesale. Of course, you must charge and collect sales tax on the retail end of the sale, or, for items purchased at wholesale and consumed rather than resold, you have to pay the appropriate tax.
