Piece or pack? Compare prices correctly.
Separate pack price from unit price with a simple calculation.
Calculate unit price
When the number of products in a pack is known, divide the pack price by that number to find the cost per item. For example, dividing the price of a pack of 10 by 10 lets you compare it with a single-item option on the same basis.
Compare the same product
Make sure the options you compare are the same in model, size, color and material. Do not assume similarly named products can be used interchangeably.
Consider your total need
Think not only about the low unit price but also the quantity you will actually use. Include shipping and other fees where applicable, and check whether the quantity shown in the cart refers to pieces or packs before ordering.
