Dear Luis,
Thanks for your message. I hope you're doing well. In your email, you asked me about shopping with my parents. Well, I usually go shopping with them once a week to buy groceries. As for promotions, I enjoy taking part in them, especially when they offer discounts or cool items like stickers! So, promotions help stores attract more customers and encourage us to buy more products.
Anyway, I've got to go now; it's time for my favourite TV show. Write back soon!
Best wishes,
