示范答案：
Yes, I do sometimes spot items in physical shops and then purchase them online—and there are also times I stick to buying in-store, depending on what I need.
The main reasons I switch to online shopping are price and choice. For example, last month I tried on a pair of running shoes in a sports store; they fit perfectly, but the price felt steep. Later, I checked a few e-commerce sites and found the exact same model at 20% off, with free delivery. Online also lets me compare reviews and alternative styles easily—something hard to do when browsing a shop’s limited stock. It’s practical for saving money and making more informed decisions.
