Conditional selection methods

Price of the product. If there is a sale price, it will be used.

Regardless of the "Prices entered with tax" WooCommerce setting (can be tax included or tax excluded), price products will be taken as entered in the edition page.

If the products haven't weight set, 0 will be taken.

The taken value will be the multiplication of Width x Height x Length. If size has not been seet, 0 will be taken.

For the volumetric weight based methods, two values will be considered: real weight and volumetric weight, and the highest value will be used. When selecting volumetric weight, a new field appears below the rules table so that you can enter the volumetric weight factor, you should get it from your transport agency.

NOTE: Volumetric set will considere all volume products vs all weight products of the group, unlike volumetric, that will compare weight vs volume product per product and SUM the result after that.

Each of them will consider, respectively, the small, middle and large dimension of the products. It does not matter if the sizes have been entered from small to large, or from large to small, in a product of: 10x15x1 or 15x1x10, the max dimension will always be 15, the mid 10, and the min 1. This method always take the products one by one, regardless of the grouping method chosen. If a product have not size set, the value 0 will be taken.

The value taken will be the sum of the dimensions. In a product of: 10x15x1, it will be: 10+15+1 = 26. This method always take the products one by one, regardless of the grouping method chosen. If a product have not size set, the value 0 will be taken.

The value taken will be the formula result: Length + 2 * Width + 2 * Height of product dimensions. In a product of: 10x15x1, it will be: 10+2x15+2x1 = 42. This method always take the products one by one, regardless of the grouping method chosen. If a product have not size set, the value 0 will be taken.

The number of products in cart will be taken, except if you have used the special action that excludes products from the following rules, or this option within Shipping Boxes: In this case, the quantity will be decreased.

The subtotal price. The difference between using Products Price (with a gruped-all strategy) and this selector, is here we can get the subtotal price after coupons application, there is: the real amount of the cart before shipping rates.

The number of groups, depending on the group-by strategy. For example: if there is 10 products in cart of two distinct shipping classes, if you set the group-by per shipping class the value will be 2. If you set it to no group, the value will be 10, and if you set group-by to all grouped together, the value will be 1.
