Is there a method to Amazon's "Add-on Item"
Here's an example. The first article is heavier, less expensive and not an add-on item but the second product is MORE expensive and weighs MUCH less but it's an add-on item. Now someone explain to me what the logic is behind this? Weight and Price has to be ruled out because my two examples don't make sense.
