In my opinion ,经济实惠economical and practical ; means inexpensive but substantial
by the way , 实惠 original meaning is "material benefit " And in many situations , it means affordable , economical , cost -effective .
Eg. 批量采购要比零买实惠很多
Buying in bulk is more economical than shopping for small quantities .
人们可以从中得到实惠
people can really benefit from it.
