示范答案：
I buy things online about 3-4 times a week—it’s my go-to way for most purchases. The main reason is convenience: I can shop anytime, whether I’m at home after work or commuting, without rushing to physical stores before they close. Online platforms also offer a much wider range of products—from daily groceries to electronics or unique handmade items—that I might not find locally. Plus, comparing prices is effortless, so I can always get the best deal without hopping between shops.
