A little strange cargo per kg is indicated as $ 3.7, the weight is taken from 100 grams, I understand this if your product came less than 100 grams, it will be rounded to 100 grams here, yes, everything is fine, I do not argue, but it is not clear to me if my product comes 550 grams and it is rounded to 600, or 135 grams and it is rounded up to 200... where's the logic? Rounding the weight does not mean that you need to round every hundred, it is no longer correct.
