We ship from Peru worldwide. The shipping costs are weight and region related. As an example (to the US): From 250g on: 21 USD, From 500g on: 32 USD, from 1kg on: 53 USD.
There are articles which are very light (like necklaces under 100g), and other ones around 400-900g (weavings).
To make the best out of the high postage means being as close as possible to next weight interval.
(1) How can I show to a customer the difference of weight left to the next weight interval?
(2) How can I show recommendations of products fitting into the weight difference between the total weight of products in his cart and the next weight interval?
Customer has a weaving in the cart (700g).
I want to show a message like “for the same shipping cost you could add….” and then it shows a list of products all weighing less than 300g (because the next weight interval with 21 USD more of shipping costs starts with 1kg).
Thank you for any hints!!!
