I am not a mania of online shopping. There is a big time gap between the previous time and the current time. So I almost can't remember the detail of the process and only remember the rough steps. So it is not so smooth each time. The main reason of online shopping is the relataive lower price compared to the supermarket's price. But I am not sure whether it is really cheaper. I am tired of comparing the different price between different sellers. It is really time-consuming. I only buy toys for my niece as the new lunar year'present.
