absolutely according advance buys calculated calculations charge charged confident correct customer don essentially figured goods help ignored includes item items multiple price products reading rule selling shipping source tangible weight zero

Hello, I've done some reading here and just want to make sure I have this right... because I will be selling tangible goods from more than one source, I can't set the shipping for every item according to weight... some items will be according to weight, and others will include the shipping charge in the price... so those that I don't want the customer charged shipping for, I will set the weight at zero? Does this mean if a customer only buys one item and it is one that includes shipping in the price, I will have set the weight at zero and they will not be charged for shipping? And if a customer buys multiple items, shipping for those I've set a weight for will be calculated, and the item with no weight will essentially be ignored when shipping is figured? I want to be confident that I have this correct! Thanks in advance for any help.

If you are using a weight based shipping rule, then yes, that is absolutely correct, products with a weight of zero will not be figured into the shipping calculations.
