(Disregard punctuation marks when entering product numbers; i.e. "27,856-4" should be entered as "278564" etc.) Click on the "Get/Confirm Pack Sizes" link.
  3. The screen will refresh with a product description for each line and dropdown list of package sizes and prices. If the product is only sold in one package size, it will automatically be selected and no dropdown will appear.

NOTE: If you need to make an edit to an address or add an attention line, department name, building and room number, this can be done inside the Shopping Cart.
