I want to order many Duplo parts. They are so heavy that the shipping cost is
higher than the price it self.
So, I want to search a store (or all stores in a country) for "Duplo" parts order
by "price per weight" up (price/weight). Finging those parts which are cheap
(relative to their weight).
This 'price density' is a bit too strange.
Therefore, I will request feature of ordering by 'weight' alone.
(I can then compare the price density mentally on my own)
